I have Vandy 2CE sigs mated with Tube Audio Design 150 pre and the TAD-60 power amp. I have changed the power output tubes to EH 6CA7 which improves the imaging and soundstage. I have had the McCormack in my system but, the TAD-60 with its 60 watts per channel beat up on the McCormack. I do not know how a modded McCormack would compare. I listen to similar music as you do and, depending on the room size the TAD-60 has plenty of power. Price should be right around what you are looking for. The 2007 model has a larger power supply so it can handle higher peaks. Don't take my word for it. Read the reviews here in the review section. Also, very important with the Vandys, get yourself a good set of speaker cable. One suggestion is the MIT shotgun. I auditioned them in my house and they were a huge improvement over the Tara Labs prime bi wire. Unfortunately they were a bit pricey for me but, I did find some Chinese cables from a dealer here in Houston that compete very favorably with the MITs. The improvement in speaker cale added a whole new layer to the music. Vandys are very reactive and transparent I found...
