When planning my trip to the EnoSound show in Bilbao early in 2018, Cayetano Castellano, Manager of Artesania and international representative as well as organizer of the EnoSound shows, revealed to me that he became co-owner and export manager for a new brand of high-end Spanish loudspeakers by the name of Kroma Audio. He said that they were really something special and that they would be one of the highlights of the upcoming EnoSound show.
The creators of the Kroma Audio products are Miguel Castro and Javier Millán. Miguel is the designer of the cabinets and Javier designs the crossovers and the fine-tuning is done together during long listening sessions because they believe that our ears are still the best adjustment tools. I have met these gentlemen several times and they are always very friendly and also extremely modest.
Indeed when I first heard these speakers, I noted some qualities that were really outstanding but because the rooms were far from perfect, I could not hear them in their full glory at that time. It wasn’t until after the guys gave an overwhelming demo later that year in Munich as part of the HiFi Deluxe show that I could hear that these speakers truly are world-class. Clearly, I wasn’t alone in thinking this as the orders rolled in and before they knew it Kroma Audio had representation in 10 countries!
This collaboration turned out to be advantageous for all involved: Miguel developed the new Organic Line for Artesania and Cayetano has enabled new business development for Kroma Audio, allowing them to grow from an accessories manufacturer to an important player on the loudspeaker market.
Kroma Audio was created out of a desire to combine the highest level of High Fidelity with the naturalness and realism of a live performance. According to Kroma Audio, there are too many loudspeakers with artificial colorations that harm the natural timbres of the instruments and prevent the listener from forgetting that they are listening to a recording. It is their aim to suspend disbelief and to reproduce recorded music with an overwhelming, realistic live-performance-like fidelity.
The cabinets are fully made from white Krion, with carbon fiber inlays on the sides. The speakers are coupled to the ground via included specially manufactured feet made of non-metallic components. There are as little as possible metal parts inside, not even screws. Instead, the drivers are mounted using thermoplastic screws.
The passive crossover is comprised of ultra high-quality components from Duelund, Mundorf and very special NOS components and is isolated in a hermetically separated chamber. The tweeter is made by Hiquphone, a relatively new company headed by the former designer of Scan-Speak drivers. The two Mid-woofers are Scan-Speak Revelator 6,5” made under Kroma Audio specifications. Nominal impedance is 8 ohms and combined with a 91dB sensitivity this makes for a very amplifier-friendly speaker: officially minimum recommended amplifier power is only 15W. The speakers weigh 100kg each and come standard in white Krion with Carbon Fiber but are also optionally available in true 24 Karat Gold Leaf finish.
Inside the Krion speaker cabinets, different kinds of wood are used in carefully selected places. Evident from the outside are the two bass-reflex ports, machined from solid wood and of a different sort and thickness for each port: cedar wood for the medium frequencies and spruce wood for the bass frequencies. Finally, there are some small wood pieces in very critical places inside the cabinet to control the energy and to achieve the final part of the fine-tuning with the most natural tonality.
The setup in which these loudspeakers will be reviewed normally consists of the CH Precision C1 DAC/Streamer/Controller and A1 stereo amp, two music servers: the Melco N1ZH and the Antipodes EX and Wilson Audio Watt/Puppy 8 speakers. For this review, the Wilsons were moved out of sight near the left wall, with their inputs shorted. As a starting point, the Kroma Audio Carmens were set up in the exact same positions as the Wilsons were.
Speaker cables are the Jorma no.3 and analog interlinks the Cardas Clear XLR. All power cables are Belden 19364 with Oyaide 004 IECs, except for the ones for the power amps which in this case both used Belden cables with the warmer sounding Oyaide 079 IECs. I also tried Transparent Super Gen 5 and AudioQuest Water cinch interlinks and the CH Precision Balanced Link XLR cables and while all had their specific benefits I found the balance best with the Cardas Clear XLR. See the Zanden review for a detailed report of the relative differences between these cables.
Ben van Leliveld and Peter Chattelin delivered the speakers together with a Zanden 3100 preamp and Zanden 8120 power amp and they helped unpack and set up. This was no superfluous luxury, as these speakers are very heavy. They come in very sturdy and luxurious flight cases with embedded wheels so they can be transported by a single person with ease but the unpacking should really not be undertaken without help. Maybe two persons could have done the job but I was glad that both Peter and Ben were here to help. When the case was upright with its lid removed, one person held the case while two others wiggled the speaker out of its enclosure. Once the speakers are set up, they move about very easily on my laminate floor and moving them around on carpeting should also be easy, as long as their feet are added only after the speakers are in their final positions.
When all was connected up, Ben made only very minor adjustments to the speakers’ positions and pretty soon we were good to go. To start off, first, we listened to the Carmens using the CH Precision A1 amplifier. The Carmens are very easy to drive and sound much more controlled than the Wilsons and so I found that the A1 could be used best with its feedback adjustment control at its lowest setting, meaning zero global feedback and only local feedback. For the most articulate and precise bass I found that a setting of 20% was ideal but on balance, for the most pleasing overall presentation with a good balance between precision and organic flow, I preferred the zero percent setting.
Listening – CH Precision A1
These speakers have superb bass. They are exceptionally linear and even-handed, much more so than my Wilson WP8’s. By comparison, the latter are a little bumpy, in spite of exhaustive room treatment. I’m sure that the Wilsons can have a perfectly flat output but perhaps only in a perfect room. The Kroma’s, however, simply perform sublimely in the same positions as the Wilsons. They reach as low as the Wilsons do, but because they are so accurate, they may not give this impression until you play a track with truly deep bass. These speakers do not add any heft to create a feeling of fullness, they simply reproduce what is on the recording. All the bass notes come out with perfect articulation and equal pressure. Regular readers may have noted how I tend to emphasize the importance of bass quality. I am admittedly a “Grundton-Mensch”, in other words, I have a preference for the fundamentals of music, more so than for the overtones, although I really couldn’t choose between the two as both are important. It is the bass, however, that forms the foundation of the music. You can have superb communicative powers in the midrange but if the bass can’t keep up, the combined sound will still be slow and non-realistic. It is the bass where the rhythm originates. For me, bass needs to be articulate, fast, dynamic and reach deep, too. Alas, all too often, depth is achieved at the expense of many other aspects, or vice versa. I don’t know how they do it, but the Kroma Carmen simply does it all.
These speakers are also extremely precise, startlingly dynamic and vibrant and utterly lifelike. This is especially evident in the midrange but that area does not stand on its own. Midrange sounds have their fundamentals in the bass and although I’m sure that the mid/treble driver is something special, it truly is the incredible coherence with which the three drivers operate that makes these speakers’ midrange stand out. Regardless of their high precision, the Carmens never sound clean or cool. Their enclosure may be resonance-free but they sure sound richly colorful, vibrant and full of life.
Piano and vocals sound utterly realistic, even more so than with the Wilsons. From the very first notes of any instrument, you instantly suspend your disbelief and succumb to the music. This is an aspect that literally everyone who visited picks up on – from ribbon-die-hards to small-speaker convicts to music lovers who have no ties with high end whatsoever. All it takes is three piano notes to convince.
The treble is also superb, not by standing out in any one aspect but because of the complete absence of any detractors. Like the bass, it is utterly linear. There is no harshness or edge nor any softening or blurring and there is certainly no dampening of dynamics but absolutely also never any edge or peakiness. Off-axis listening turned out to be another strong area, the speakers sounding extremely even, regardless of where you are seated. Even right next to the speakers, the output is still very linear. They are not ribbon-like in that they do not sound super-airy or super-refined but on the other hand they have incredible resolution and refinement, making me realize that the typical ribbon aspects that I used to chase after for so long may be nice to have but don’t have so much to do with accuracy or relaying the musical message.
I mentioned their coherence – I’m really not exaggerating when I say that it is as if the speakers’ three drivers work as a single driver. Whenever these speakers play, I find my foot tapping, always! They even make the Wilsons, one of the most coherent systems that I have heard so far, seem a little rough around the drivers’ transition areas. The Wilsons have great PRaT and they sound very fast indeed but they’re just not as linear as the Carmens.
There is absolutely no perceptible crossover between the drivers, no phase issues and no highlighting of any frequency range. All 3 drivers simply operate in utter unison. This makes for a very fast sound and combined with their high efficiency and linear impedance this also means that you don’t necessarily need to partner them with the fastest, most dynamic or most powerful amplifiers.
