Pass Labs Aleph 1.2 // Vintage Class A Monoblock Amplifiers // 07109 / 07110

The Pass Labs Aleph 1.2 monoblocks are what happen when Nelson Pass decides to throw efficiency out the window and build an absolute monster of a Class A amplifier. Each of these 130-pound behemoths pumps out 200 watts per channel—but at a cost. And by cost, I mean your electric bill will double, your listening room will double as a sauna, and your friends will question your life choices when they see you installing these with a forklift.

But if you’re after pure, effortless, single-ended Class A magic, you already know those are sacrifices worth making.
