Rushton pretty well has taken the words right out of my mouth. I can't speak as an owner but I have a good friend with the full blown Aesthetix Io Sig. and it is pure pleasure! As for myself I recently acquired a Rhea and Calypso. Even in a head to head with the Io it comes real close to everything I have ever wanted out of a tube phono amp and paired with the sister preamp it works out real nice. IMO other than Ralph's Atma-sphere MP-1 w/phono, I have not heard anything close to Jim White's Aesthetix gear. A lot of folks have mentioned Lamm and Janis gear repeatedly through these threads on the subject of tube amplification, I have never heard either of them, but would like to very much.
