ARC CA-50 vs. C.J. CAV50 any experience out there?

Has anyone had the chance to compare the Audio Research CA-50 integrated and the Conrad Johnson CAV50 integrated? If so, what are your thoughts?

Bump. I'd be really interested in this comparison as well!

Get a ARC VSI55 which is way more transparent and a true giant killer with it's passive preamp.

The CJ will be warm with sluggish bass, the ARC CA-50 will be little congested. The ARC VS55i will be amazing!
