Tube integrated amps

Three excellent choices, good luck.

just a small 2 cents, most of you know much more than I.

I drove an 86db speaker to comfortable levels (in a small room) with a 10 watt Baby Sophia. The sound was wonderful.

I now have a Rogue that would drive the cones right out of the boxes if I'd let it and it's only 55 watts. But......love it as I do, the small room gets hot, hot, hot and it's wintertime now.

FWIW

I'm driving 86 or 87 dB sensitivity ProAc speakers with the CJ CAV50 integrated tube in triode mode (22wpc): no problems at all in a medium sized room. I'm in SF and Nycjdc's welcome to come over and listen. Two integrated tube amps currently in production and available used for under 2K are the Rogue Tempest II and the VTL IT-85; I think they're both 60 wpc rms or more, and well spoken of.

The tube issue I was concerned with was not primarily loudness, but spectral balance. If Dynaudio is right, and they should know, that the impedance curves are benign and linear, than it should be much less of a "problem".

Dynaudio recommends 60 wpc for smaller rooms, and at least 80wpc for bigger rooms.

Given the specs - 6ohm nominal impedence and sensitivity of 86db I would tend to agree with Dynaudio.

If you really want tubes I'd suggest you look at using a hybrid amp. These speakers were not designed to be driven by a tube amp.
