The new LUNA sports many interesting and, above all, clever design solutions. LUNA is truly a world-class amplifier design, with several really well-thought-out solutions.

The Luna does not colour the sound in a classic, stereotypical tube way. And certainly not as much as one would expect from an amplifier operating in push-pull mode, in class AB and with EL34 tubes. The first conclusion that can be drawn from longer listening sessions with a truly diverse repertoire is that the FEZZ Luna sounds, above all, extremely clean, subtle and undisturbed.

I started listening to Luna with electronic repertoire, namely the album “Inks” by AES Dana. It has that combination of synthetic, low bass impulses and a textured tonality. Already on the title track, the Luna showed that it does not only control the bass, but it is also capable of generating a very evocative, close and tangible soundstage. At the same time, it was neither the soundstage nor the bass, but the ability to perfectly combine micro and macro dynamics that was most surprising on this particular album.

Luna is exceptionally good at rendering that sonic plankton, all that micro-information that sometimes is lost, even with some tube amps. It is so good, in fact, that I reached for the “Celestial Echo” track from the album “Convergence” by Malia and Boris Blank. Malia’s vocals in this were phenomenally rendered and placed in an airy space, considering the price of this amplifier.

The point here is that Luna has one feature that is rarely found in this price range. On good recordings (especially those where the vocals were recorded with care), the new FEZZ amplifier does not add that extra haze that sometimes appears in some tube designs in this price range. Yes, you can hear that you are dealing with a tube, but you also get a very strong sense of directness in the sound.

I knew this amplifier would be good, but I didn’t expect it to be that good. In fact, FEZZ has created something here that can easily be considered as a milestone. And I am not only referring to the extremely well-thought-out design of this amplifier, which is also really user-friendly at the same time. The new Luna also represents a new level in terms of sonic prowess. It is an amplifier that can be described without hesitation as a something of a long-distance competitor. Does it have any flaws? Considering the price, I don’t think so. Sometimes, these truly refined sound designs do not evoke really strong emotions at first. However, the longer you listen to the Luna, the more you simply appreciate its tuning. It is rare for me to recommend a device with such fondness. Editor’s Choice Award.
