Well, one reason I said what I said is because I have witnessed it with my own ears. I had a perpetual ground hum with the Krells, although slight and you had to get close to the speaker to hear it, but it vanished when I got the McIntosh amps. Before selling the Krells, I tried rewiring the outlet and it would not go away so maybe they were doing it(?).
I also want to point out that when I said "go for McIntosh et al." I was not ruling out Krell entirely. Perhaps the models I had were not up to par or something. I have heard other Krell systems that sounded very good and so I am sure some of their amps/systems are fully worthy of their high praise. I did afterall love them for a few years.
I will say that my only disappointment with the McIntoshes is the fact that they ARE so revealing. Some of my not-so-good recordings do not sound great. However, play a well recorded CD and feel chills come over you. Love it.
