Kas power consumption at idle
You can not even think about the cost of power in standby, or you will not enjoy the wonderful sound of the amps.
I sold a pair of 450mcx that had reasonable consumption at standby, and bought evolution ones that spin the meter quite well in standby mode. Higher wattage when fully powered on. The sound difference is over the top. Way over. And I was convinced the 450mcx was some of krell's best work, but the evolution one is it.
In the early 90's I listened to the kas amps quite a bit. They are incredible. Enjoy every day with them as they are very special amps.
Would love to a/b the kas and the evolution ones at some point.
Cheers
