So you want solid state strength and grunt, but with the space and fluency of tubes. The Exicon ECX10P20 and their complementary EXC10N20 lateral Mosfets, two per channel, make for the perfect ending for a circuit that begins with the gorgeous sounding Siemens C3m, and then has the power supply to play into any impedance; 8/4/2/1. In stereo form we're talking about 100 watts into 8 ohm biased heavily into class A, and thrice that with the mono blocks, if you really do need endless power.
