I'm going to expose the limits of my knowledge here, but this is something I want to know. I've read explanations of it before but I'm still not completely clear on it.
What is the advantage (if any) of a receiver/amplifier with high current capability? Harman Kardon (and other HK owners) wants me to believe that although my 525 is only rated at 70 Wpc, all channels driven, it favourably compares or even surpasses competing models in terms of output and sound quality because of its HCC: +/- 45 amps. What exactly does this mean and how does a receiver/amp's current capacity affect output levels, sound quality, distortion, etc.? As I said above, unless my mind played tricks on me, I noticed significantly more output, and *clean* output, over my previous Sony DE685 (I think that was the model #). I also noticed a fuller, richer sound. I know that the HK's 70 Wpc was "honest" compared to the Sony's 100 Wpc (IOW, all channels driven, 20-20,000 Hz). But does the higher current capacity play a role here and if so, what is it?
