Nice Review ..... finally
http://cheaptubeaudio.blogspot.com/2013/10/review-ifi-iphono-nagra-bps.html
Conclusions (taken from the review)
The iPhono is unusually fine-grained and quiet (not just at its price, but comparable to most products regardless of price). It makes the music flow naturally, and has excellent rendition of hall sound. It doesn't play to the gallery, instead rewards in the long term.
The iPhono compares well to more expensive phonostages (even to the Nagra BPS reviewed below), and so is surely a BEST BUY. I think mid-priced phonoamps, not to mention budget ones, will have a hard time going up against the iPhono.
In the company of all the phonoamps I have, for three months I listened mostly to the iPhono (save for comparison purposes); that should tell you more than this review how satisfying the iPhono is!
Take time to run-in and check for isolation.
