Which 300B SET for SF Guarneri Homage?

"heard what that same speaker was capable of when paired with an amp that offered reserves of power."

I should have written:

heard what that same speaker was capable of when paired with an amp of comparable quality that offered reserves of power.

Phaelon,
A keen observation you make, all amps are`nt equals just looking at power ratings. As others have pointed out the Frankenstein is far from a generic 300b SET amp. For sure the`re 300b amps that would fail at driving Don`s speakers(no arguement) but with the knowledge of personal ownership and an understanding of the design priorities and it`s sucessful implementation, plus hearing this amp with several moderately effiecient speakers mate very well I felt Don had a good chance at sucess. I don`t question Daveyf`s experiences with this speaker, he was simply unfamiliar with this particular amplifier.It`s worked out well for Don and that`s all that matters.

I agree with you Phaelon; your observation of how a 'phile's jaw drops once they hear their less efficient speakers driven by a quality amp with power reserves, is my general observation also.
I actually am beginning to think that in many ways Charles1dad and I are talking of the same thing. It's true, I have not heard the Frank amps or with the SF GH's combo. He also apparently hasn't heard the SF GH's and therefore neither the combo. I don't question his experience with the Frank amps; He doesn't question my experience with the GH's. Turns out that the OP seems to be happy with the combo...which is clearly to do with his expectations. Good for Don.
Would this combo work for me or other 'philes with different expectations?
Who knows, BUT I very seriously doubt it would be to my liking.
Luckily, to each their own applies in this hobby..:0)

Daveyf,
Well said, personal preference is the key to ultimate satisfaction with one`s audio system. You have to know what sound/music reproduction makes you happy and just try to obtain it to the best of your ability, many roads lead to Rome. It seems we both have sucessfully found our paths.

I was leery of the Frankenstein's "lack" of power- until I got them. It's a damn robust 8 wpc, and I like to listen at pretty loud volumes. Couldn't comment when the thread came up, because one is never sure how a purportedly low power SET amp will perform with a not so sensitive speaker....but I had a strong hunch he'd really enjoy the Frankensteins. They are remarkable amplifiers- so much so that my beloved MastersounD Compact 845 amp is off on temporary loaner duty while I continue to explore what the Frankensteins can do. They're that good. Don, what I can tell you is that if you like the Franks, consider getting the Coincident Extreme IC's for them- opens up a whole new door of transparency with the Franks. Did you get them from Israel with the Shuguang Treasure Black Bottles? If not, I'd say go for that, too. Yet another decent upgrade to the amplifiers.
