I love my 500 A. I use it mostly for Jazz and acoustic stuff and it sounds great. I bought it partially re-capped and had a technician finish the job. My only complaint is the tapered RCA plugs and the difficulty in using decent interconnects because of them. I had the bright idea of replacing the plugs myself, then I open the cover to get to them and went, "Nope". Other than that, I really have no complaints.
