Tsiteerime, mida on kirjutanud Audiomat Opera Ref. 12 kohta Paul Candy väljaandes 6moons.com:

“For me, the Opéra Référence was to musical reproduction what Heifetz was to the violin, Kleiber to the baton or Callas to the voice. Forget the usual HiFi boom, bang and sizzle; the Opéra simply plays music. I don’t know how else to say it. In fact, I’m a trifle disappointed in my review of it. I can’t quite find the words to express how good I think this amp is and what, specifically, it does so well to be so superior. You need to hear that for yourself. Suffice it to say, my quest for the ideal integrated might be at an end. If you ever tire of listening to this amp, you might as well throw yourself under a bus. Your zest for life will have surely faded at this point. Nothing I have heard to date has gotten me so close to the music and the artists’ intent than the Opéra Référence. A truly wonderful amp.”
