Need advice on amp to drive Vandersteen 2Cs

I would consider the Odyssey Audio Stratos power amp or the McCormac .5 or any of them because of their lack of grain. Plus they both will control the bass and deliver very good soundstaging. I think your weak link is the
preamp. I would go with a VanAlstine tube preamp with phono stage. They can get pricey but there are bargins around. The Audible Illusions 3 preamp is a very good choice too. Don't forget the Conrad Johnson preamps with phono are a very good choice. I think by going with a quality tube unit it will open that soundstage and make things more listenable. The Denon amp is not a bad unit but from what I remember it was strictly mid fi. But a good preamp with phono could improve on it. Find a friend that has a tube preamp with phono and listen to it with your Denon amp. Or try a tube linestage with the Denon and see if you get any improvement. Don't hotrod any gear. Have the preamp plug directly into the power amp and use very good quality wire and interconnects. You may be surprised what you hear.

I had the 2C for 6 years and the Quicksilver silver monos, M80 or M60 were all magic on them. For SS, the B&K, Muse 100 were also good, but the tubes were magic....I even liked the ARC D300 or D240. Jallen

I owned the 2C and drove them with a upgraded stereo 70 with an ARC-6B preamp. Great combo in the right room. I'll never forget listening to the 2C at Music by Design, (now gone)in northern California with an ARC SP-10 preamp and ARC D-115 amp. Wonderful combo. Lot's of choices.
Audible Illusions 3 A,B preamps with Quicksilver amps mid mono's and Silver 60's sound great!! Belles and McCormack solid state amps are really good as well. But, to my ears the 2C sounds best with tubes.

I had the 2CE sigs and since upgraded to the 3aSigs. I had a McCormack DNA1 but, it was bested by a TAD60 and now a couple of TAD 125s. Not true that the vandys are not a good rock speaker. That's about all I listen to. They are very non fatiuging and can pack a nice punch with the right electronics.

My 2 Ce Sig II were originally mated with a Rogue Cronus
and upgraded RCA Clear Tops with outstanding result if
you have a medium sized room but I upgraded to the Belles
150A Ref and it's stunning!
