@ Almarg, Hi, I am sorry, I did not mention my source of info was from krell, when we were dicussing the input sensativity of the krell 700cx, the 18 volts is max, that is never used!, the amp gets 6 to 8 volts,pending what model krell pre-amp being used, that has nothing to do with cast, thats balanced!, then I was saying a source componet with a real analog or transformer based volume control running direct to amp has the performance I mentioned above, not the digital volume control that likly will do bit stripping of the signal!, and if you actually have a very high quality pre-amp that has the transparency of a direct to amp source componet has?, thats likly due to the gain that pre-amps have, you hear more information, more sound, sometimes, more dynamics, pending on the pre-amp used, not really more transparency!,
