I had a problem with a fairly bright system, especially with the metal drivers of my Monitor Audio GR-60's. I too was looking for an integrated with a good deal of brunt and control but with warmth and detail. The Electrocompaniet ECI-3 was my dream find. It has the warmth and romance of tubes but with the critical detail and accuracy I was having a hard time finding. It would be worth giving it an audition if you have a chance.
