The Quicksilver M-135 monoblock amplifiers are a powerhouse option for audiophiles who want a serious dose of tube-driven magic in their stereo system. These amplifiers, rated at 135 watts each, are designed to give you that classic tube warmth with enough muscle to drive even the most demanding speakers. With their pure, all-tube design and hand-wired circuitry, the M-135 delivers a sound that is rich, textured, and incredibly dynamic, letting the music flow with a natural, effortless quality.
The build quality is another major highlight. These are hand-wired amplifiers, emphasizing durability and ease of maintenance — a hallmark of Quicksilver’s design philosophy. While they look like a throwback to another era, their performance keeps up with modern expectations, easily driving even demanding speaker setups with grace.

- Liner Notes
The new KT Mono amp retains the high damping factor and low distortion of the Horn Mono but with enough power to handle inefficient and difficult to drive speakers. The amplifier accepts KT66, KT77, KT88, KT90, KT99, KT120, KT150, and KT170 power tubes and when ordered with KT150s will produce 100 watts. It also has low distortion all the way up to full power but at reduced power gives the efficiency, finesse and delicacy of a low powered amplifier.
