FEZZ Luna review – an important milestone

This directness, and this should be viewed as another important point, is very similar to what you usually hear from good single-ended designs or solid-state amplifiers designed strictly for signal transparency (ie. Those usually low-power, high-bandwidth designs with low amount of output devices). Speaking in more absolute terms, the Polish amplifier brings the foreground a little closer and plays rather up-close. However, what it offers in the foreground, closer to the speaker line, is really very credible. At the same time, the new Luna does not try to present the listener with tube sound in the stereotypical sense of the word, but rather offers its tangibility and plasticity while maintaining both contour and dynamics.

FEZZ Luna is also one of those amplifiers that simply gets out of the way of the music. Or at least it really does everything to do so, bearing in mind its price. This was quite obvious once again on Portishead’s “Roads”, where Beth Gibbons’ voice was perfectly suspended in space. And at the same time, it was presented up close. And if I were to return to the topic of “tube in a tube”, now would be a good time to do so. It was precisely on a repertoire such as Portishead’s most famous album, or Morcheeba’s “Big Calm”, that you could hear the signal passing through vacuum components. Because when we look in absolute terms, Luna will, of course, play on the warm and more saturated side.

We have this additional element of musicality here, but it is also embellished and goes hand in hand with the amplifier’s very good grasp of all objective aspects of sound. The bass on Hans Zimmer’s “Why So Serious?” was being controlled and it had energy. Of course, large and expensive power amplifiers do those things on the lower end of spectrum better, but even in this track, Luna surprised us with how dynamic and lively everything sounded. What’s more, here too, the amplifier perfectly conveyed the atmosphere and energy of the recording. This brings us to another question – what is the difference between UL (Ultra Linear) mode and triode mode?

Let me put it this way: it’s still the same amplifier, but with a sound that leans just a little more towards a good pentode signature. Here, you can simply hear the sonic flair of the EL34 tubes, which is why so many people like it. At the same time, the amplifier still retains the characteristic clarity I mentioned earlier. The presentation in the UL mode is more expansive, the tone is more warmed up, and you can feel that the amplifier simply has more contour and its own character in this mode. The bass dynamics are also more spectacular. However, it is not as if there is a huge difference between these modes. And, of course, what someone will choose here will depend not only on their preferences, but also on the speakers and the rest of the playback chain.

FEZZ Luna – summary (and some interesting conclusions)

I will try to put it as short as viably possible. 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. However, for some, it may actually be too mild. 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. If any of you have around 2.5K Euro to spend on a good amplifier (and not necessarily looking for a tube one) please take a look at this new offering from a Polish company. It is rare for me to recommend a device with such fondness. Editor’s Choice Award.
