Stereo Times reviewed the EVO very recently too. They are going to regret using up so many superlatives on the other reviewed digitals.
I've hear all but the PS, and that is not in the same power league I need. IMO The eAR is hands down the very best amp ever produced.
I've run some of the best solid state amps, and tube amps too, and using the eAR improves on the sound in all categories. It's mids and highs sound like tubes, except with total clarity into the musician. The Bass is as powerful as with the biggest Krells, but natural at all frequencies. What's more, the eAR exudes power like you've never witnessed.
The ICE module has greater potential than the TacT and TRI Path modules. Only Rowland, and Acoustic Reality has produced home audio amps with ICE. The Rowland uses digital switching in its power supply, while the AR uses analogue. The difference is easily heard.
