A2.640 Amplifier



The new A2 is a top-level, fully-balanced design. It supports Class A amplification by leveraging graphine,  a high-tech heat-dissipation material. The design is a combination of both the traditional and the radical. The output chips have two levels, 10 pairs of op-amp, more than 600 watts of RMS power per channel, and a peak output of 2100 watts per channel.

Praise from Secrets of Home Theater and High Fidelity:

"The Starke Sound A2.640 is the best amplifier that I’ve heard, period. Other amplifiers do come close, and for less money, but only in some respects. The Starke edges out its competition with outstanding performance in every sonic area."
