Power Amp for Hyperion 938


I am running in a pair of new Hyperion 938 in a 12ft x 21ft room. Any recommendations? Budget is around $2000-$5000; prefer to spend less if possible. Used is also ok. Prefer tube amps(KT-88, 845, 300).

My setup

Marantz SA-14 ver2 (modified)
Supratek Chardonnay preamp
Hyperion 938
Audience AU24 IC and speaker cables + jumper

Vocals, Jazz, Classical, Chamber, no rock.

Any input is much appreciated. Thanks.

Thanks all for the response. Because I have the Supratek Chardonnay preamp, I think I will try out the new Supratek Malbec 50W amp using KT-88. I hope these are heavenly combo.
Ethifi, did you notice any problems with bass in your listening room? My is almost the same size (12ft x 17ft) and I am affraid that it is too small for such a big boxes.
Krzycho : the 938 are very sensible to speaker cables.
To get something good you need the good cables, i used to run my 938 in a small room with no problem at all.
I have no problems whatsoever. Surprisingly, the bass is not bloomy at all. Maybe because I am sitting 40% along the long wall. In my previous place, I was sitting to the back wall and the bass was very bloomy. In fact, after over 1.5 months run-in, the bass on the speakers is beginning to sound more punchy. When I first received the speakers, I complained to the dealer that bass was almost missing. My current amp is a cheapo-sort of amp which I bought over 10 years ago; it is the weakest link in the system.

Agree with Ndeslions that cables are also important. I have the AU24 and they are wonderful.
I noticed that there is an importer in US that brings the Sovereign brand. These are the absolutely best transistor amplifiers in the planet. I own the Sovereign Director preamplifier and the Sovereign Power amplifier with my Hyperion 938 and I still haven't heard a system costing up to 100.000 Euros that can be compared with mine. You better have a listen soon....
