Speaking of the Adcoms...Now that I'm the proud owner of a GFA-545II and GFP-565, I actually sort of miss my GFA-535 and GFP-555, especially the amp. Maybe it's only what I was used to. With the GFA-545II, I just can't seem to find a comfortable listening volume. I had not heard the cries of brightness, but I do now often turn down the treble...much more often than I did with the GFA-535.
