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.

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.
Get a pair of BAT Vk-60s and strap them as monoblocks (120wpc). All-triode operation. Will be plenty loud. Can be had for under $5k for the pair I'd think. Will easily kick the arse of anything by Rogue, and will be quieter than the big CJ monos (12s, 5s, etc)

ED_Sawer. To each their own. I auditioned a mono blocked pair of BAT VK150's driving the speakers I own & prefer the Rogue. May depend on what type of music you listen to, or could have just been a system matching or personal preference thing. Seems like the BAT excelled in body and what some folks think of as midrange magic (and others call coloration) and the Rogue was a bit more solid state sounding. Have not heard the VK150SE's. FWIW, it is bugging me that I never got a chance to hear the CJ140.
Sonic Frontiers is, as I am sure you know, no longer in business, but I understand that service can be obtained through a sister company, Anthem.

A close hi-fi friend of mine had the Power 3's for over four years. They were incredibly reliable (they never even went out of bias) and sounded great for the money. These days, they can be had for +/-$3,500.

Good luck.
