Which 300B SET for SF Guarneri Homage?

Guys, I think you are missing the point here a little... Sure the Frankenstein COULD work and maybe the OP would be happy with them. BUT, the Frankenstein might not/probably wouldn't work with the SF GH's. It seems to me that if the OP doesn't have the opportunity to listen to this combo himself, it would be far more prudent to acquire an amp that very definitely WILL work with the GH's.
The Dragon amp by the same Co. WILL work with these speakers; not COULD work with these speakers-- I think we can all agree on that.
As an owner of the GH's, and having tried this very speaker with low powered 300B amps, I know as a FACT that the300B amps that I have tried with this speaker do NOT work well ( at least in my small room). Unless you own this speaker and the amp in question, all else is supposition. At the end of the day, UNLESS the OP is able to hear the Frank/GH combo for himself, then it is a crap shoot as to what the result will be for him.Knowing these speakers, like I do, I personally wouldn't take that risk. Just IMHO.

NO DON'T EVEN THINK ABOUT IT!!!
The Border Patrol 300B cannot express any high frequencies when mated with Guarneri Hommage that acts like a HF filter!!!
The Goldmund Mimesis 8.4 monoblocks 185 Watts cannot express their speed & finesse either with Guarneri that acts like a brake, destroying the tonal quality of both!!!
Don't get fooled by their size or the tricky specifications:
They need plenty of room to breath their image & voice capabilities and they are VERY demanding of the amplifier that feeds them.
As a comparison example I let you know that a Proac Response 5 in the same small room (3x5 meters) with the same set-up, feels much better and plays the same SPL for half the volume setting!!! (and loves the Border Patrol as much as the Goldmund. In fact I could never manage to clearly prefer one over the other so I pick them both for it).
The Guarneris are going to mask the delicacy of a highly sophisticated but week in current power amp. Also they refuse to open-up the midrange and keep even an average bass foundation if your amp does not have plenty of reserve power both with a full body & robust personality. (in a contradiction the Krells can't do it right).
Make no mistake here. They want big & "beefy" amps. (At the Sonus Faber factory they use an integrated Accuphase).
Also, the minimum room for them is about 5x6 meters otherwise they cannot image the scene (no soundstage at all).
The absolutely best amp that I really love to pair with them is the Jadis Defy 7. (despite I am a 300B SET fun).
I'm afraid you have to choose between SET & Guarneri.
But in a small room & with a preference to low listening volume level...I'm sorry. I wish you to get rid of them and find a way to better serve your listening & not your decorative needs. You see the reviewers are not allowed to inform the people for the specific needs of the Guarneri so, we can assume that is just another small & manageable mini monitor...
So far from the truth!!!
Good luck

FWIW: find a way to listen the Transmission Audio M1i

George, I do agree with you that the GH's like a little stick up front. Along with my 65 watt/ch tube amp, I also use, to get a different perspective, a 250 watt/ch Rowland amp. The GH's have no problem at all with 250 watts/ch! OTOH, I don't agree with your comment that the GH's need a room of 5x6 meters otherwise they cannot image!... I have mine in a 3 X 3.5 meter room and they image very nicely and are able to portray depth well. This room size is not ideal, BUT you can get the GH's to work in a small room, albeit with a lot of experimentation.

I drive my GH with a Viva Solista SE amp, no issues!

Great sound, dynamics, punch... Everything is there.... Saying that, and since the 845 tube is a different thing than a 300B I should audition first.

I appreciate all the informative opinions to aid my decision.
The ideal thing would be to try it, but that won't be possible.
An additional thing is that i have a SF Gravis active sub to help with the bass (cutoff below 42) connected to the amps outputs; i don't know if this factors at all on the equation.
My personal experience is that the SF GH are driven pretty easily by the Pass, but this is 30w.
Cheers,
