Hi all. I performed the Musicoat upgrade that audio_optimizer recommended on my SCD-777ES. I treaded all integrated circuit chips, disk shaped capacitors (not can style), axle leaded resistors, diodes, and diode heat shinks. This stuff ($105 shipped) really works. The digital hash is gone, I hear the air pulsating through the wind instruments, the decay is enhanced, i also hear the performer take a breath which I couldn't hear previously (enhanced resolution) on my reference disk, and I know the background noise is lower (I can hear more hiss on a super quiet passage I didn't hear before). I can now increase the volume on my Aloia amp/preamp without hearing so much digital grit/sizzle. Will order more to do amp and preamp. System includes Talon Khorus, 777, Aloia, and Audio Tekne cables. Thanks, Mike
