CD Player Debate

Any thoughts on the SimAudio SuperNova vs the Audio Research CD8?
I own a CD7 and its hands down the finest piece of audio I have ever owned. I prefer ARC as they also have a great service dept.

I have to agree with Weiserb, the CD7 with the power supply upgrade brings it pretty close to the CD8. And it is a real bargain used. I have not heard the SimAudio SuperNova so I can't compare the two. But I did listen to a number of players before I bought my CD7. Nothing came close to it in my system. The other player I did not get a chance to hear and that I am curious about is the PS Audio.
Any thoughts on which would pair better with a McIntosh C2300 preamp and MC252 amp? If neither, any other suggestions?
Anyone compare Audio Research CD8 with Luxman D-08??
