Looking for warmth

FWIW, although I agree with Onhwy61 in general, your post doesn't really help me in understanding your needs. You ask for more warmth but I have found that when a lot of folks do that they are in fact confusing warmth (as described by Onhwy61) and the need for a reduction in upper mid range glare most often caused by electronics, especially a lot of CDP's, speakers, and room placement and acoustic's.

In looking at your list of components I would rule out the Vandies as being a contributor to your problem - they are not inherently bright or cool speakers. Your amps are not known for being warm - to the contrary, but whether you need new ones or not is yet to be determined. (On that subject, if the amps are a problem, I would highly recommend that you not spend the money for two amps for these speakers, just get a better amp and run them full range).

I can't help you with the NAD stuff - I'm not familar with it. But I'm always suspicious of CD sources aas being a particular source of the problems your post suggests.

If you are trying to eliminate brightness this can also be changed by room placement, toe in, and 1st reflection points. Best to rule out set up as a source of your problem before replacing anything.

- pair of pse studio v monoblocks or muse mono blocks or quick silver monos (lose the adcoms)
-audible illusions L1 preamp
-muse model 2 dac or marantz cd player

First of all I would like to thank everyone for their suggestions, from the most radical, "start all over" to the best one liner..(the link to stoves)LOL....
I have already taken a persian rug off the wall and placed it on the floor using onhwy61's advice and today I will try using only the 545.
I will start looking for a decent tube preamp, though I am currently stationed overseas...it will cost quite a bit to ship over, hence the lower price range that i can afford right now.
I am a bit hesitant to sell the Adcoms...I like them ! but, If I find a good McCormack at a good price, i'll just give them to my son...
The quest goes on....

get a better pre and cd player

I will disagree with most, and agree with Wadia150. First of all, it is hard to find an amp that is smoother in the mids and sweeter on the top than the "sleeper" (of a Pass amp), the Adcom 545. Ahhh.. read the ba-zillion consumer reviews in audioreview.com if you don't beleive me. The problem exists in your NAD pre-amp, the 555 and ~perhaps~ your cables. The 545 Adcom is not the Holy Grail for transparency, nor is it layered in it's depth,... BUT "open", "strong" and "sweetly detailed" it IS. I have reservations (imho) about the Adcom 555. It is nasty, dry and can bite little chunks out of you. I don't like it. It is mearly a 545 on cheap back alley steroids. It has enough of them in it to make itself sick and ill tempered. It has collapsed it's own soundstage, dropped it's depth into an burning abyss and pushed it's evil manables into a room full of hot coals. Whoever is left to suffer along with it will scratch at their ears like mite infested felines. Get rid of it. As someone else suggested, perhaps try the 545 by it's lonely ole' self for a short while. Think of crossing at a lower freq. and perhaps with another cheap, but "grip"-heavy amp... Parasound, lower-end Bryston.

My vote is for a ride out the window for the NAD followed by the 555 tied to a cinder block.
