I used a Janus from Aesthetix and it was magnificent. I had to sell it to raise cash just recently, and boy was I sorry to see it go. My separates (Blue Circle linestage and EAR 834p) that I still owned went back into the main system, and what a disappointment it was to hear it! (And those are GOOD products!)
I'm a believer in integrated phono stages now. The one drawback is that many integrated phono stages do not have the gain and loading adjustments that we all want to have. The Janus did have gain and loading adjustments, however.
Cheers.
