External DAC for Sony SCD-777ES

I use a balanced theta Pro Gen V with Genesis Digital lens, Behringer DEQ 2496 for digital EQ and a Sonic Frontiers Ultrajitterbug. My SCD-777ES is stock. The difference in sound quality without the DEQ (i.e. no digital room correction) is vast and well worth the upgrade. I never heard a modified Sony so I can't comment on differences between it and stock, however, I suspect the fully balanced class A, discrete output stage, of the Theta would be hard to beat. With digital EQ providing room correction CDs are actually very enjoyable compared to vinyl. Vinyl though is still supreme.

Cut to a simpler approach. Go listen to a Cambridge 840 player. I think you will find its DAC well beyond any outboard. Get a dealer to loan you a unit, then you can compare to your current setup. The 840 squeezes out everything there is in red book cd's. I also have a 777es (no mods), together with Cal Labs Alpha and Sigma tube DAC's. The 840 took the red book's to a new, and better level of listening.

You have done all you can do IMO maybe some power supply mods. Vinyl is obviously your thing so I would put my money there.
