During the review period for the Ayre QB-9 DAC were there any comparisons done between it and the C-5xeMP or CX-7eMP? I know because the QB-9 only has a USB input they wouldn't be truly a direct comparison but it would still be interesting and somewhat informative. The comparison would be helpful for those that are trying to decide if their next digital front end will be a DIY server OR a traditional CD player. It would be a great follow up, hint, hint.

I know Wes Phillips did listen to both the QB-9 and the C-5xeMP, but I don't know why he didn't specifically comment on the comparison in his review. I did have the QB-9 briefly in my system while the review was being prepared, and I did feel that the C-5xeMP did have a slight advantage playing both CD files and hi-rez files that I also had on DVD-A. The player, of course, will also play SACDs.
You'd expect the differences to be small, however, as the QB-9 and C-5xeMP have the same digital filter. The QB-9's output stage, BTW, is the same as the new revision of the K5-xe preamplifier.
