Sony SCDXA777ES vs Sony SCD1 ?


I am interested in listening comparisons between the stock SCDXA777 and the SCD1. Also does anyone know if the SCD1 uses multiple paralleled triple DACs as does the XA777 and are the DACs similar or which are better? I will be listening on Quad 989s powered by Atmasphere MAImk2s and Aesthetix preamp. Info on system your comparisons were made on would be useful.

As I understand, the SCD-1 does not have the the triple paralleled DACS as does the XA-777ES, because the SCD-1 is a two channel only machine having only one DAC per channel. The XA-777ES also has newer more advanced DACs than the SCD-1. In multichannel mode, the XA-777ES uses one DAC per channel, but in two channel mode, it puts three DACs per channel in parallel. I've owned both, although not at the same time. I think that on SACD they're about equal, but on redbook CDs the XA-777ES wins hands down. Both are heavy and well-built, but the refinement of a second generation machine is obvious in the XA-777ES.
The SCD-1 is better on both redbook and scad handsdown. The scd-1 was constructed as a statement piece and as such is untouchable by sonys lower level players. And is even untouchable by many esoteric interpolation cd players.

However if you want multi-channel you must go with the XA if you want two channel then the scd-1 is simply the best sony offers. And modded it is considered the equal of the 20k machines on redbook or sacd.

There are many threads on this supject; simple do a search.
I'll agree to disagree with Czbbcl. You might want to check with Dan Wright at modwright.com about the differences between the players and get his advice. He's quite knowledgeable about both, and I bet he'll tell you to go with the XA-777ES. I've been very impressed with his mods, although I'd take CD 12 over the modded SCD-1 if I had the 20 grand to spend on a CD player.
I have discussed this topic with several modders and retailers while some prefered the xa most agreed the scd-1 was the better player for two channel; better parts and simpler circuit. However, in the end it is personnel preference and the size of ones pocket book as well as system matching.
