Amp suggestions for Avalon Radian HC


Just bought a pair of used Avalon Radian HC speakers and wondered if anyone can tell me which reasonably priced amp would best suit the old classics. I currently have a Tube Research ST-100 but I just wonder if they would be bettered served with something else?? Anyone out there have experience with this speaker. Any input would be appreciated.

Hello Carey,
There are a lot of amps that will drive the Avalon Radian HC's.
When I got my pair I used a pair of Adcom 565A's for a while, then I went to a Bryston 4BST. The Bryston sounded the best of the two.
I now have a pair of Spectral DMA360's and of coarse they sound the best.
The HC's were designed to use MIT cable and Spectral gear.
Look in the archives of Stereophile January 1996, vol. 19 NO. 1, very good review of this combination.
The best thing to do for the HC's is to get a pair of MIT 850 triads. These cables were specially designed for the HC's. When I first got my HC's I ran them with a pair of MIT MH770 CVT cables. When I bought a used pair of MIT 850's it was amazing. The HC's should never be used with any other cable. The HC's sounded very good with the MIT770's but after using the 850's they really sounded great. This will be the biggest upgrade you can do for the HC's.
On amps I would go with Spectral, the Bryston 4BST did sound very good.
But please get a pair of MIT 850 triads. the best money you will spend if you plan on keeping the HC's.
If I sell my HC's the MIT 850's have to go with them.

Greetings,
Some people have had good luck with hi-end tube amps. The Radian's need a lot of power.
The MIT 850 would make more of an upgrade than most any amp IMO.

Try an Audio Research amp? The dealer I bought my Spectral amps from feels that the only tube amp that can drive the Avalon speakers properly are the Audio Research.

Try to buy the MIT 850 Triads first, they need to be used with the speaker, than listen to see if you need more power. You will then have the cables if you change out amps.
I would recommend that if you stay with tubes also make sure to have tube pre-amp IMO.
If you lived in Alaska I would have you over to hear the difference.
