Audio Advisor says: "In fact, the 851W is so powerful that a normal AC power cable can’t deliver the current required. We supply the 851W with its own dedicated, high performance 20 amp AC power cable."What a load of r****sh
This is it at clipping tested by Newport Labs.
8Ω loads, the 851W was able to deliver 223-watts
4Ω loads, it delivered 351-watts per channel
2Ω loads, and able to deliver 509-watts
The clipping indicators came on right at the onset of clipping
Cambridge pulling more than 200-watts from your mains power supply during normal operation, and nearly 700-watts when you’re listening at high volume levels.
