hey. can you list the info on where to find out about this mod?
The Stan Warren Mod was highly recommended by one of the partners at Perpetual Tech. Evidently PT liked it so much that they will honor the warranty after the Mod. It costs $300 and there are a few threads scattered here and there about it (search under Perpetual). You could also call PT, as they do endorse this mod.
I had a SCD 777ES and sold it to buy a SCD 333ES + P3a with Dan Wright Mod and Monolithic supply. (I am waiting til the software comes out for my speakers before I get the P1-a). I have to tell you that the Perp Tech dac BLOWS AWAY the 777es on Redbook CD's and really aproaches SACD performance.This Dac is supper detailed with an incredible soundstage. The 777ES to me sounded rather dry and thin, no matter what I did it never came to life, except with a few of the best SACD's. So try a P3a with your SCD'1. I think you will be very pleased.
