Help choosing tube monobloc's


At present I am running a Sunfire Tube Preamp and Sunfire Signature power amp.
I would like to introduce monobloc tube amps into the system.
The speakers are Kef Model Four~Two so they like to have power (I was thinking 150 wpc min.).
I have been thinking about a used set of Sonic Frontier power three's.
My budget is in the $5000.00 to $7500.00 range.
I mostly listen to classic rock, with a minor amount of easy listening, folk and classical through a Sonic Frontier Phono 1 tube amp (can there be too many tubes in the signal path) and Oracle table
I would appreciate anyones advise on tube monobloc selections.

Jeff Jones, I have no personal knowledge of the Rogue 150s, but usually when UL amps are wired or switched into triode, the maximum power reduces TO about one-third or just a little more. I'd be surprised if the Rogue 150s have more than 60 Watts max. in triode...

...which MIGHT be enough, depending on one's listening levels. I have and LOVE Quad 989s, which have a sensitivity rating of around 86dB. I was driving them full range with tubed monoamps that use 4 6550/KT88/KT90s in either UL or triode and are rated at 100 Watts in UL. (Never got an owner's manual so don't know what the triode rating is.) My room is fairly large at about 3200 cubic feet, and I listen to large-scale symphonic music. The '40-Watt' amps had plenty of power, never clipping. I recently replaced them with Antique Sound Lab Explorer 805 DTs, mono SETs with 50 Watts max. power. Again, I have plenty of power and NO clipping.

883Dave, I suggest you try some tubed amps before you commit your thou$andS.

BTW, UL amps run in triode sound to me simply richer and more like real music in the mid and high frequencies than they do in ultralinear. There was a long and thoughtful discussion of UL v. triode here a few months ago; you might search for it.

How about AES/Cary Audio Sixpacs? I have a pair along with one of their preamps - they are gorgeous!
Jeffreybehr,

According to Mark O'Brien @ Rogue, the M-150's put out ~100 watts in triode mode.
Don't forget Aronov LS-9100 tube monobloc's which provide the reality of a performance in your listening room, and the best in bass for your classic rock (and everything else). Some days,I seem to be a one person Aronov cult believer, although in other threads more voices are added to the chorus of praise.
