MrTennis,
Thanks for the feedback. I have only listened to ARC CD7 in my system, I think it's strength is that it put the listener at ease with the music, it puts the listener in a very relax mood. It certainly doesn't do all the 'audiophile' things as good as players such as Esoteric. In fact, i find that the CD7 has a much more laid-back presentation than Esoteric X-01, the image size of CD7 is smaller and more 'diffuse', but the CD7 has a very sweet and airy top end which means you can listen to it for a very long long time.
I haven't had the chance to listen to AMR 77, but from what I read, the AMR77 seemed to be more 'forward' sounding, more 'meaty', harder bass, but perhaps not as sweet as the ARC CD7 on the top end? Pls correct me if I am wrong.
For the record I don't own the CD7 because I am primarily a vinyl guy.
