Reference amplifier review, 6moons.com, March 2022
“The new Soundastic also offers a slightly better resolution and differentiation, and this characteristic feature of the DM-250, its exuberant temperament, has been tamed a bit (hence more refined). The superiority of the tested integrated and talents of its designers are best evidenced by the fact that the latter difference is not manifested in any decrease of the dynamics or energetic abilities of the Reference, but in a better grip exerted over speakers, and this relaxed, highly sophisticated way of playing music, which results in a fuller, richer, and better differentiated, ergo more complete presentation.
The treble with the tested integrated seems more refined. It is more open, vibrant, full of energy, perfectly differentiated, but also smoother, or simply put, shown in an even more realistic, natural way.” – Marek Dyba
