Best amp to Partner with Jeff Rowland Criterion


I have a Rowland Crtiterion Preamp and Rowland 312 Power amp. The 312 is amazing in its neutrality and transparancy, but it's NOT the last word in dynamic capability and low end frequency extention. Anyone had a chance to try out other power amps with this world class Pre?

Sorry Osvaldo for the confusion, what I meant to say is that in my system, the bass of 312 does not sound weak at all. Last night I put on Dvorak's New World Symphony under Leonard Bernstein and the Israel Philharmonic, and the initial low brass chorale in the 2nd movement was simply hair-raising in its power. . . David, when are you coming for a visit?

An 825 stereo + 312 stereo byamped combination would be very intriguing. . . the only problem is that I have truly no idea when the 825 will be released.
I have a 301 on the way to drive the very power hungry Revel Salon 2's, I've enjoyed reading your posts and will let you know how everything works (I will be using the Meridian 861 in the front end.
Sounds exciting.... Did you buy 301s new, or you purchased the set advertised by David Weinhart on Agon? Heard Criterion + recent production 301s on Revel last July at Renaissance Audio in Dallas, and the result was wonderful. G.
