I use three MC611s to drive my L/C/R speakers. The cables from my preamplifier are Wireworld Eclipse 8s, and my speaker cables are Wireworld Silver Eclipse 8s. Power to these amps are via Shunyata Venom HC power cables to two Shunyata Denali 2000/T power conditioners and then via Shunyata Delta power cables to the amplifiers. I am simply delighted with how well this “amplifier subsystem” performs.
