Re: Parasound HCA 3500 Amplifier (SS)

John - I really enjoy working on both of these amps. The main differences that I see that makes them sound different is:

1) circuit board partitioning between predriver and output stages is different in the two amps
2) Predriver power regulation is different

I believe that #2 accounts for most of the difference. After CES, I plan to redo the regulation on the JC-1 predriver board and see if that makes it sound more like the 3500. I will probably add low-voltage regulators, so it is double-regulated.
