Pylon Audio Jasper 23 Floorstanding Speakers – Musical HIFI Experience Art
Pylon Audio Jasper 23 is a $6399 USD Flagship pair of High-End Speakers designed for the best audio experience you can have. Today we review the Jasper 23 and will also compare them with the best speakers that we’ve reviewed including Audience ClairAudient 1+1 V5 (3900 USD), Pylon Audio Diamond 30 MKII (3000 USD), Amphion Argon 3s (3000 USD) and Pylon Audio Jasper Monitor 18 (2950 USD). While some of the comparisons are also from Pylon Audio, as we will explore, each pair has its own identity and sonic signature.
Introduction
Pylon Audio is by now a super popular Speaker manufacturer from Poland, but it started very small, in 2011, built by childhood friends Mateusz and Mikolaj, out of love for music and passion for creating something good. Pylon is inspired by a family heritage in the furniture industry, and Mateusz’s family was known for high-quality woodworking, opening the path for them to create a family-run business, initially creating just the speaker cabinets. This path took the entrepreneurial spirited duo to create Pylon Audio. Today, Pylon audio is already gaining traction and by many music lovers is considered to be a better choice compared to Focal, Elac and other titans, thanks to the high-end build of the Pylon speakers as well as the exceptional sound they create, and being quite a bit more affordable than the competition.
Today, Pylon Audio has a state-of-the-art facility spanning over 3300 m2, and employs a team of over 50 skilled specialists. To create the sound they deliver, Pylon has partnerships with Mindorf, Seas and Scan Speak, as well as producing components in-house, like electroacoustic driver elements, crossover coils and many others. Jasper is currently the flagship line of speakers produced by Pylon Audio, and it represents engineering perfect and top-notch sound with a stunning design. This line includes two floor-standing models, and one monitor with an optional accessory stand. Today we review the middle of the range, Jasper 23, which is not the largest, but we did cover Jasper Monitor 18 already, so we can draw comparisons between Jasper 23 and the other models made by the company.

Build Quality – Design
Pylon Audio Jasper 23 is the company’s flagship, but this time encapsulated in a smaller and slimmer frame, perfect for smaller rooms, compared to the Jasper 25mkii speakers that the company has as the flagship. Right from the start, Pylon knew what they were aiming for, including superior craftsmanship, and top-notch sonics that the Jasper line is known for. To achieve the sound, Pylon Audio employs special acoustics, enabling the smaller Jasper 23 to produce sound in the lowest registers.
At their core, Jasper 23 is built with drivers from Danish Scan-Speak, models carefully selected based on acoustic measurements as well as subjective tests. The famous Revelators 15 are responsible for the midrange and the low end, using the famous notches to reduce diaphragm distortion and dissipate standing waves. For the top end, J23 uses a silk dome tweeter, with one of the lightest vibration systems, the driver having a weight of just 0.18 grams. This results in theoretically extreme speed and a snappy response.
Built upon years of research, Pylon used an anechoic chamber, laser accelerometer and designed the perfect working conditions for the drivers. Those cabinets are built from high-grade thick MDF boards, and the front and back are made in Sandwich technology. The speaker frame has additional reinforcements to ensure that the enclosure is free of any resonances, and the characteristic curved front and back prevents the formation of standing waves in the enclosure and equalizes the acoustic centers of the speakers in the midrange, for the ideal consistency and soundstage.
Technically, Pylon Jasper 23 has an impedance of 4 OHMs, and a nominal power of 100W, with a Max power of 200W, for a SPL or efficiency of 88 dB. The drivers used are a dual combo of Scan-Speak 15W/8531K00 for the mid woofers and a Scan-SpeakD2608/913000 Tweeter for each speaker. Physically, they weigh 26 kg per piece, and are designed for rooms between 18 and 35 m2 in size, with magnetic grilles included and a W / H / D size of 166 / 992 / 401 mm. You can order the Pylon Jasper23 in a multitude of colors and finishes including American Walnut Natural Veneer, with 25% gloss lacquer, Morocco Ebony Natural Veneer, White High gloss, White Matte, Black High Gloss or Black Matte. You can also order a custom pair with either a matte or gloss lacquer with RAL palette colors, including multiple green, orange, purple colors.
Subjective Usage – Placement
First thing you will notice about the Jasper 23 is how reliable, solid and well-built they are. Pylon made sure those will survive any shipping conditions, and the internal frame just feels very rigid and high-quality. This time around, I kept the magnetic grilles on for most of the time as they really do not affect the sound, and they do protect the drivers from dust and damage. I feel like Jasper 23 is better made than most speakers, and you can see that it draws inspiration from high-end wood furniture processing. Each finish, each party is so perfect, everything so refined, and the speaker is separated from the pedestal on the bottom, creating an impressive first impression.
With the power connector at the back, you do not have to use a biwired input, but you can if you desire to. You also have to mind the bass ports at the back as Jasper 23 is a vented design and will produce a different sound if it is sitting too close to the back wall. I have placed them in multiple rooms, multiple locations, through various degrees of acoustic treatment, and I found that they sound excellent as long as you allow them at least 10 cm from the wall behind, as that is enough for the system to work properly, and they very quickly reach peak performance if you give them this space. Lateral separation between the speakers does need to be at least 2 meters for an optimal sound, but you should always keep in mind that having an equilateral triangle between you and the speakers tends to produce the most balanced sound, and it will sound at their peak intended performance.
Even so, my setup usually has me sitting in a nearfield monitor position, while working at the computer, a situation in which the sound of the Jasper 23 is still excellent. The only difference I have noticed is that if I sit nearfield, I have to angle the speakers in such a way that they are firing at me and not at the room. Basically, I have a very wide desk, around 1.8 meters wide, with the speakers sitting at another meter away on each side of the desk, so the whole setup has the speakers sitting at 1.5 meters on each side for me. In this setup, Jasper 23 is aimed at me, so I have them placed a bit further in the back, allowing for enough space to create for the sound to be perfect. Technically the height would be better if I was sitting a bit lower, so that my ears match the level of the tweeters, but it is close enough as it is. I have also tested them in a traditional HiFi listening position, but I tend to see how much I can squeeze performance wise from the speakers by having an odd placement and what’s the limit of what you can do with them.
Thanks to a very wide dispersion for both the midwoofer drivers and tweeters, you really don’t have to worry almost at all about the placement of the Jasper 23. You can basically sit anywhere as long as you are within their firing range and you will be fine. They have a dispersion cone of around 110 degrees, which is very wide, so you don’t have to have them angled at you and you can adjust your position a lot without the sound changing. This applies to both the lateral and the vertical dispersion, and Jasper 23 fires really nicely in all directions, basically they can fill a room easily even if you have them misaligned relative to you.
You also don’t have to worry about the ground on which they are placed, as I have tested Jasper 23 with most wooden floors, hard wood and soft wood, as well as concrete floors, but the pedestal foot that is built into them along with the mini feet seems to already do a good enough job for the speakers and basically they end up sounding exactly the same on all floor types. Acoustics of the room are mildly important, more important if you are sitting farther away from the speakers, but after doing tests in a couple of different rooms with different materials I realized that the simplest tricks are to have a thick carpet that covers as much of the floor as possible, and if you can have walls that are not empty, as in, have some objects in the room, that is plenty acoustic treatment. Heavy and thick curtains help a lot, and Jasper 23 is very consistent across listening rooms. They do tend to sound a bit better in smaller rooms, from 12 m2 to 30 m2, especially if listened to in the traditional hifi sense, of sitting farther away from the speakers. Nearfield listening is more flexible, but 30 m2 is pushing it for the room size, and I would suggest going with Jasper 25 if your room is larger than 30m2. The effect that happens is that bass is more plentiful, more present and deeper in smaller rooms, while the sound is more engaging, more vivid, and more present, while above 30 m2 the bass is less present and the sound is less powerful. Using different amplifiers also has a pretty drastic effect on the sound, but I would not call Jasper 23 as picky, they can sound great from an affordable entry-level AMP if you need them to, but they will scale and improve with a better AMP.
Sound Quality
Pairings – As Jasper 23 has been my full system for a really long time now, to allow for proper burn-in, it also has seen a large number of amplifiers and I am not able to explore its pairing style. It does not take a lot of power and voltage to get the sound loud with Jasper 23, but it is an ultra revealing pair of speakers and it requires a clean, crisp DAC and AMP combo, as it will reveal the differences between amplifiers. Furthermore, Jasper 23 will take advantage of the max resolution your system delivers, but moving the sub-bass and creating proper extension means that youi need a strong amplifier like Keces S300+, but you can get a solid sound with a set of Topping B100 Monoblock AMPs in Class B, or the Argon Audio SA-2.
Overall Signature – Pylon Audio Jasper 23 depends a lot on the amplifier that is powering it to drive them well, and when they are driven properly, they produce the most vivid, engaging and revealing sound that I’ve heard so far, with a strong emotion, upper midrange bite, super extension up to the highest octaves and a wide, holographic soundstage. If possible, I would push them laterally as much as possible for an increase in soundstage size, as they stay layered, separated and crisp even if you force them to be 4-5 meters apart. Pylon Audio managed to create Jasper 23 with a pure, analytical, but musical and juicy texture, they are perfect for basically all music styles, but especially nice with classical and acoustic instruments, rock, metal, EDM, Pop. I don’t think there’s anything that they don’t do well, and you can say that they’re a pair of speakers that never misses.
Bass – At their lowest, Jasper 23 is one of the speakers that climbs the lowest, reaching around 30 Hz in my smaller rooms and 35 Hz in my larger rooms. They will render a fast, highly technical bass but with a nice amount of bounce and impact, being perfect for fast, complex music, as the driver is very capable and will always render every single detail in your music. As the driver is tuned for speed rather than size of bass, Jasper 23 sounds controlled, dynamic and technical, but has a natural bass, with zero bloat and zero distortion. When underpowered, the bass quantity decreases, but the driver stays controlled and there is no increase in the distortion, rather the sound gets more airy and more gentle, for example with Orchard Audio Valencia at 17W of stereo power. With a really powerful amplifier, the bass gets far more punchy and deeper, and with Keces S300+, Jasper 23 sounds full, pops life into music and creates a highly engaging bass that is bouncy, turning my entire house into a club.
Midrange – Pylon Audio gave a superb voicing to Jasper 23, with a juicy, reference tuning. You will feel pressed to find any coloration at first, as they sound immediately natural and the whole tuning really grows on you. Jasper 23 can render micro details, textures with both precision and musicality, creating a fluid, juicy sound that appeals to both rock and metal, pop and basically all music styles. It is crazy just how good they are with both male and female voices, and everything sounds emotional, true-to-the-source and brilliant, as Jasper 23 can make you feel like the artist is playing right in your room, but with natural spacing between instruments and an insane definition. They tend to reveal more detail and information than monitors made for studio, but they do have a tendency to always sound enjoyable, and nothing really sounds offensive when Jasper 23 is playing it.
Treble – With a sharp, crisp and airy top end, Jasper 23 renders cymbal crashes with clarity and zero distortion, playing a different tone and type of cymbal crash for every song, creating a tuning and signature that gives music energy and presence in the top end. This is especially welcome with classical and metal, rock styles where Jasper 23 renders more micro details and information in music than any of the other speakers I heard to date. They extend up to 20 kHz, but the treble character is mostly silky and enjoyable, yet bitey and present enough to keep music engaging, interesting, give glow and soul to a guitar solo, and make the drum kit sound metallic when they used metal, and wooden when the band is using wooden kits. It is insane how many types and signatures of cymbals Jasper 23 can render, and it makes other speakers sound limited, as they create many more flavors and types of cymbals, showing how different the mixing and master of certain songs is.
Dynamics And Textures – With the highest dynamic range, Pylon Jasper23 can render extreme differences between quiet and loud passages with ease, and regardless of how well powered they are, they stay dynamic and crisp. It feels like they render a far higher dynamic range, more information and more contrast in music than all of the other speakers I reviewed to date, making music stand out far more, each stem and each instrument is more vividly presented and differentiated from the others. One super interesting effect is that textures feel cohesive, despite the slightly faster speed in the treble, treble is silky and enjoyable, midrange is super juicy while bass is bouncy and full, creating a tuning that is endlessly enjoyable. At times it feels like there’s a very slight V-Shaped or U-Shaped tendency, as J23 can give a bit of extra life to bass and impact and a bit of extra energy in the treble, but I never felt like the midrange is pulled so I wouldn’t say they are colored in any way, rather they allow each song to play exactly what is inside that song.
Loudness Saturation Gradient – Jasper can sound really loud, achieving 110 to 120 dB with ease, especially in a closed space. They have no trouble sounding linear, with the same tuning and same ultra low distortion at all volume levels, but they seem to prefer a powerful amplifier with a high headroom, as they can sound more bouncy, and with a fuller bass, and at the same time I have been enjoying them daily with both very high, very low and medium volumes. I am willing to say that they do have that type of ultra low distortion that makes me want to up the volume to the max I am allowed by the neighbors, wife and family. It is a speaker you never grow tired of, always surprises in many different ways.
Soundstage – You can slightly change the soundstage width and depth by placing the speaker farther away from you, and farther away from each other, but in general they produce a wide, holographic soundstage with exceptional layering and a strong imaging with superb stereo. Even in a very small room with the speakers being close together and listening to them in a nearfield position, they sound wide, stereo separation being strong and they create a rich layering, with each instrument playing in its own individual layer, each bit of information is rendered vividly with a superb separation. They do tend to sound slightly analytical and will not over blend the layers even in an open space or huge room, always each layer is well-defined and the soundstage stays wide and holographic at all volumes, all room sizes and through all amplifiers I tested, which I personally enjoy a lot.
Comparisons
Pylon Audio Jasper 23 vs Amphion Argon 3s – (6399 USD vs 3000 USD) – While trying to include as many comparisons as possible, I realize that I started with one of the weakest competitors, both in price but also in performance. Argon3s is built fairly well, it has a nice overall construction quality, but it comes with a less premium overall finish, while Jasper 23 feels more premium and more sturdy. The idea behind Argon3s is that both drivers are protected at all times, it is smaller but incredibly hard to drive, and despite having a lot of tech focused on giving it a wide dispersion, it is far more fussy about proper placement giving me frustration from trying to use them, while Jasper 23 is so easy to place and use. Sonically, Argon3s sounds quite bright and aggressive, crisp but lacking bass and with a smoother treble that is not focused on clarity or resolution. Compared to them, Jasper 23 is far more resolute, more resolving in the midrange, has a more natural treble that is silkier and easier on the ear, and a far deeper bass with more impact, better nuance, better impact and a much wider soundstage with far better instrument separation and spacing between instruments. If you are looking for a good monitor, Pylon Jasper Monitor 18 would make a better choice as it has many of the characteristics that I love in Jasper 23, while Argon3s has potential, but falls short in resolution and depth.
Pylon Audio Jasper 23 vs Pylon Audio Diamond 30 MKII – (6399 USD vs 3000 USD) – Naturally, you’d like to know how the two floorstanding speakers from Pylon compare, and to be fair, the experience is quite different. I do find both to look stunning, but Jasper 23 is smaller, and takes less space, easier to place in the room and a bit less directional, while with Diamond 30 mkii you fall out of the dispersion cone a bit faster, and their hotspot or sweetspot is a bit more narrow. While both need a bit of space, Diamond 30 mkii likes to be placed farther away from the wall in the back, but can fill up a larger room more easily, thanks to both the larger physical size and larger number of drivers. Both speakers require a good source, but Diamond 30 is a bit harder to drive, consuming more power, needing a beefier amp and sounding a bit quieter at the same volume level as Jasper 23. Sonically, both are very detailed, but Jasper 23 resolves more details, sounds more engaging and more punchy, deeper and more powerful with more control and more depth to the bass. This being said, Diamond 30 mkii does not have a sound quite as neutral, and it ends up sounding a bit more sweet and airy, it is a very pleasing tonality, and while not exactly a 1:1 copy of the track, it is extremely relaxing and fun to enjoy. Jasper 23 is more energetic, reproduces the source material more accurately, reveals more details, it is technically a much better speaker with better overall performance, but this doesn’t leave Diamond 30 mkii in the dust, but rather showcases that they were made for a different listener. Diamond was made for a more casual listener, someone romantic who wants to enjoy a sweeter sound, while Jasper 23 is made for someone who wants to hear more, especially someone who enjoys a more detailed sound. If you have good acoustic treatment, you can get a really good performance from Diamond 30 mkii, but Jasper 23 is not as needy with the room, so it is a top option if you don’t want or can’t get a good acoustic treatment in your room.
Pylon Audio Jasper 23 vs Audience ClairAudient 1+1 V5 – (6399 USD vs 3900 USD) – You can get an interesting pair of monitors from 1+1 V5, but the drivers are so much smaller for ClairAudient compared to Jasper 23. This means that Jasper 23 can deliver a much deeper sound with far better sub-bass reach, while 1+1 V5 will stop much higher. Although Jasper 23 uses multiple drivers, it sounds almost as cohesive and fast as 1+1 V5, although ClairAudient reveals more details in the midrange, while Jasper 23 reveals more details all across the frequency ranges, rendering micro textures and bits of information for every instrument. The soundstage that Jasper 23 creates is much wider, deeper and has a stronger layering, with a higher instrument separation, while 1+1 V5 sounds more intimate and a bit more creamy. This is because 1+1 V5 has a smoother tonality for the treble which is also handled by the same driver as the mid and the bass, while Jasper 23 sounds sharper, more defined, has more bite and more energy, as each range has a dedicated driver that powers it. Overall, while 1+1 V5 is a great monitor for exploring the micro details in the midrange of your music, for audiophile listening Jasper 23 is superior and fuller, needs nothing else to be enjoyed, and is currently one of the top sounding speakers that exist in the world.
Pylon Audio Jasper 23 vs Pylon Audio Jasper Monitor 18 – (6399 USD vs 2950 USD) – Jasper Monitor 18 is part of the same series as Jasper 23, as both are released recently and are part of the same family, so you would expect them to sound similar and to react similar, but in actual practice Monitor 18 is harder to drive and requires more power to get as loud as Jasper 23, and Monitor 18 is a bit more fussy about amplification, working better with ultra dynamic, high power amplifiers, while Jasper 23 sounds great out of most amplifiers I tested. Sonically, the two speakers are rather different, with Monitor 18 sounding quite a bit warmer, thicker, with more mid bass, a smoother treble and a bigger sound in general. The dynamic range is more acute on the Jasper 23, which sounds far more analytical, more neutral and revealing, although both sets of speakers produce a huge image in the soundstage and both create a grandiose sound. Monitor 18 sounds far bigger than it looks, and sounds bassy and full, while Jasper 23 sounds far more detailed, more crisp and more precise than it looks, it feels like the ultimate, absolute revealer, extracting, revealing but also painting a musical image that is enjoyable and fun. You will be happy with either, and you can rest assured that both would be incredible, but if you want a full and warm sound, Monitor 18 delivers that while for an analytical, crisp and fast sound, Jasper 23 delivers that better.
Value – Conclusion
While Pylon Jasper 23 looks more refined than most speakers on the market, it also has a higher performance and better price performance ratio than most. As someone who attends High-End society and who has a considerable collection of speakers and headphones, I think that Jasper 23 is right at the top in performance, and with a bit of acoustic treatment, you get more performance out of them than out of most speakers in the whole world. Value is exceptional and not just for the sonic performance but also long-term reliability, construction quality, and design. You can be sure that a pair of Pylon Jasper 23 in the house is a speaker set that your wife will love, as they are truly beautiful, arched, the same way that high-end luxury furniture is.
Award – I find Jasper 23 to be the best sounding pair of speakers that I’ve reviewed so far, it is simply the most engaging, has the best technical resolution and revealing ability, and despite the high price, it also has basically the highest price to performance ratio, being convenient to use in both small and medium rooms, with no fuss about the AMP quality, DAC quality, just doing their part in sounding excellent in all environments they’re placed in. This is the pair of speakers most deserving of a place in our Hall Of Fame, and will not replace prior Pylon models as they serve a different market segment and are made for a different listener.
You can have one of the most beautiful and most reliable pair of speakers if you chose Pylon Audio Jasper 23 as your next music companion, and you will have a highly resolving, technically capable and engaging sound that has a vivid presentation outlining the beauty in music all while keeping a profound bass and bright, airy treble. This is a top choice for all music listeners and right now it is the best pair of speakers I can recommend.
