This is just an initial impression after only 10 or so hours of playback but...In the name of all that is Good and Mighty... This is the best CD/SACD player I have ever heard under $6,000. Multi-Channel SACD is simply a bonus. Every one of my SACD's has a brand new life. I'm still deciding on the redbook side...I have a PerpTech modded P-3A DAC which has been just amazing, and on a few CD's I'm thinking the XA777ES comes very very close to besting it. Even if it doesn't, the fact that it is light years ahead of the 333ES as a transport, which is what I was using to fed the PerpTech DAC before makes the CD's that much better. So the 333ES is off to the Bedroom to replace a CA7ES carousel Redbook-only player. I am just marveling at the sheer awesomeness of this machine. It is better than the 777ES from what I can remmeber and I didn't have enough time with the SCD-1 to really make a fair comparison. I'll report more after I have at least 100 hours on it.
