Conrad Johnson Premier 350. AMAZING amplifier. Detail/soundstage is incredible, tones are natural/lifelike, and power on tap is very impressive. I never imagined that such detail and soundstage was present in my music. Sound is not too warm, not too cold and sterile. I struggle for any other adjectives than it sounds lifelike. Whatever information is on the recording will be extracted in lifelike/natural tone, detail, and soundstage. It will drive any speaker you can throw at it. Every time I press play, I marvel at how transformative this amp has been to my system.
After a 10-year journey, I'm done (as far as amplifiers go). I love this amp.
