Peamp/Amp for Thiel 3.7


I recently acquired the Thiels when I moved to a larger hifi room. The electronics I currently use are a Aesthetix calypso and a Primare A32 amp (250w/ch). The sound of these components was perfect for Wilson Sophias I had before I moved overseas but seem a little light on the low end now. I did not percieve the 3.7s to be thin on the low end when I auditioned them. In any event, I am considering upgrading my amp/preamp to better units to take advantage of the glorious coherence and soundstage of the 3.7s. If I have a budget of say $8-9000 for both, what would be a recommendation. 3.7 owners' opinions especially welcome.

For sure a Krell amp. Either the FPB series or older KSA "S" series. I have two buddies who have the KSA's and love them for their Thiels. One has the 3.7's and the other the 7.0's.
For preamps I would say either a Krell or a BAT. At your budget maybe a VK50 or higher SE series would sound great if you want a tubed preamp. I am sure there are alot of nice preamps that will be recommeded that go with Krell amps. Also maybe a Thor or Dodd preamp could be a winner. Of course this is just my 2 cents.
I am getting the same speakers soon. I will be using my existing BAT VK-42SE pre and the Bryston 7B-SST. I may spring for the 7B-SST2 or 28B-SST2 if I the stock market is good to me.

I auditioned the 3.7's with all Classe gear and it also sounded great.
I auditioned them with a Classe preamp and Mac monobloc amps. The room was heavily damped. I like the idea of the BAT option. I was thinking about the Vk51se/600se combo.
