“The Spanish firm Bonysound presented their Symphony II acoustic columns.
Driven by ATM electronics of which the PAM-2 preamp, PPM-1 phono stage, and PDAC1 DAC were housed in very small but precision-made full-aluminum enclosures. The mono power amps, too, are made of solid aluminum and were presented in an interesting two-tone color option.
Soundwise, the system played differently than what could potentially be expected from the speakers’ warm and all-wood appearance and the speakers actually seem to sound more in line with YG Acoustics or Gauder Akustik speakers. Extremely coherent, precise, transparent, and refined, this system was all about subtlety and precision. It’s not a warm and cuddly or rose-tinted sound. But neither was it hard or forward or edgy in any way. And although I have not heard any ATM gear before, it seems that these components are very transparent and highly refined.”

“That no one expects to install this stage on their equipment and be immediately enchanted by its sound… because that is precisely its greatest virtue: let the rest of equipment “sound” without interference, without coloring, without underlining anything and without taking anything away. After that first moment we will discover that this amplification, despite its affordable price, is not only a very beautiful box, but possibly the last stage we need on our way looking for the ideal sound system. That we can have this technology at such a reasonable price and with such a striking aesthetic, thanks to a national manufacturer, is to be in luck: congratulations.”

“The EPM-1 offers the advantages of a good power amplifier of transistors in Class A, with a rich and aggressive-free timbre that reminds me a little something of the best valve amplifications, but with a unknown strength and precision for vacuum tubes in bass, and a rare definition and extension in treble. During the weeks I’ve had it at home it has worked flawlessly. Except if you have very low sensitivity speakers and/or a very large room and a lot of fondness for the great musical works that we hear very loudly, this stage could be a perfect “end of the road” at any price and I can give you my highest recommendation .”
