Considering a new amp for my Vandersteen Quatro CT


I've been using a Bryston 4Bsst2 with my Vandersteen Quatro CT for the past 5 years.  This was not an amp I purchased for the Quatro, just one that I happened to already have.  It is about 12 years old. It has been a solid performer and I have no specific complaints....just curious what a different amp might offer.  My preamp is an Audio Research LS-15.  There are three amps that have been recommended by various sources.  The Ayre VX-5 Twenty, The CODA Model 8, and the Moon by Simaudio 760a.  These are all in my general price range.  Anyone have experience with any or all of these?  Which would you think would be the best match with my speakers?

IME you would be more impressed with a better preamp than changing your amp.

I also have a pair of the Vandersteen Quatro CT and use the Ayre 5 Twenty-series products (KX-5, QX-5 and VX-5 Twenty’s) and the sound is great. That said, I am looking to upgrade my speakers to possibly the Kento Carbon or Model 7 mkii if or when I find a suitable used pair at a good/great price.

Have you considered the Vandersteen M5-HPA amp? For what it’s worth; While I have not heard them, I was told they sound better than the Ayre amps.  There is a used pair for sale in Colorado.  They're asking $11.9K

I will echo Jim’s @tomic601 recommendation of the Vandersteen mono’s. No doubt an obvious system symmetry approach.

But, if more than you want to ‘pony up’, I recently added a pair of used but excellant Belles MB-200 mono blocks in my system driving my Treo’s. Belles just knows how to make everything he makes musical. Also, a great fit with my ‘new’ Belles Aria Signature preamp. Happy camper.

@twoleftears Very good recommendation I always forget about Belles.
