Tube Amp for Green Mountain Audio Callisto


i'm considering switching to a tube amp to drive my GMA Callisto speakers and hoping to get recommendations from folks that have done so. What tube amps would pair well with the callistos?

The speakers have the following specs:
Impedance: 4.8 Ohms, +/- 0.75 Ohms from 100Hz to 20kHz
Sensitivity: 90dB

What would be the minimum power i can get by with? i don't listen at ear bleeding levels... maybe 80 db 12 feet from the speakers.

thanks in advance for any suggestions!

I have a Response Audio/JoLida 60 wpc tube amp, as well as a Mapleshade-modded 18 wpc Scott. Both sound fantastic with my Callisto. With it's 90 dB rating, most any amp over 10 watts will drive it. Basically, it comes down to quality versus quantity with this speaker- although more power is always good for speakers IMHO. enjoy!!!
