A massive, high-quality power supply with a custom toroidal transformer delivers 250W per channel into 8Ω and 500W into 4Ω (with the AC line held constant), with the first 12.5W per channel in pure Class A. Classé has worked to preserve complete separation between channels, using hand-laid 6-layer circuit boards for shortened signal and power paths with the lowest noise.\u003c\/p\u003e\n\u003cp\u003eConnections are Furutech rhodium-plated RCA and torque-guard speaker terminals, and the amplifier stands on custom-made Navcom feet to absorb vibration.
