Which 300B SET for SF Guarneri Homage?


Driving my Guarneri with a Pass Aleph 3 amp(with audio aero capitole mkIISE cdp+pre), which goes quite well, but thinking of upgrading amp to a couple of 300B monoblocks...
The thing is this is a tricky change because, among other things, the Pass is built like a tank and is an excellent amp. So I want to make the decision carefully with no hurries...
Considering as an option the Coincident Frankenstein's but i'm not too informed about tube amps.
I listen to all sorts of music though fav is Opera, so my expectations with the change would go on the line of getting a more real life experience.
I wonder if anyone had any experience of driving these 87db sensitivity, 6-8ohm speakers with a SET and would appreciate opinions or suggestions

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,
Dongiovanni, I don't think having the sub help with the bass is going to make much difference. As I stated above, the GH's need a little stick up line. The Pass
at 30 watts has the ability, current wise, to drive the GH's to a satisfying level in your room, helped by the fact that you are not asking it to push much bass. An 8watt 300B SE amp is a different deal. It could work, BUT I doubt it would be satisfying at all; as Flg2001 pointed out, the 300B tube is not like an 845 tube or 211 which in the Dragon puts out 75watts/ch. Since you are unable to listen for yourself, then you had better get return privileges from the dealer/manufacturer, if you insist on trying the flea powered amps.
I forgot to mention that I use a Velodyne DD18 with the GH with good results, the sub fills the <45Hz that the Guarneris miss to reproduce, I cut the sub at 90dB with a soft 12dB rollout.
