Which 300B SET for SF Guarneri Homage?

Daveyf,
We both can agree that listening to the GH/Frankenstein combo would be ideal. I`ve not heard this GH just as you`ve not heard the amp in question. I did place this amp on a friends 89db/8 ohm speaker in a larger room than the OP`s room and they sounded very good and strain free. All 300b SET amps are`nt created equal and yes, power supply and transformers matter greatly. Based on my experience wirh this amp(which the OP specified by the way) I simply feel it could be a good match. Regarding numbers some are more relavant than others. Certainly in this case the known load characteristics of a speaker is critical when considering a match with SET amplifiers as oppose to just knowning the wattage rating without context.Can we also agree that all 10, 50, 200watt etc. amps don`t preform the same despite identical power ratings

I second one of the earlier posters - Canary CA-339 - 50 watts of push-pull 300B power. Everything you like about 300B's but with real world power.
Built like a tank and weighing nearly the same.
Available for reasonable amount used on Audiogon fairly regularly.

I think the OP may be getting a little confused at this point. Will it work or won't it? My answer still is, "it could".

I haven't heard the CF's paired with the GH's so I don't know how "that" pairing would work and even if I have, what works for me may not for the OP.

What I gleaned from reading the topic was:

His 30 watts from his Aleph 3 was sufficient for him.

He likes Opera (midrange?), he's not looking for louder, he wants a more "real life" experience and wants to try a 300b. I think the "right" 300b amp might give him that (for ultimate purity, try and stay single ended). My Cary 300b's put out 15 wpc. That's 3 db less power/not a big deal/might work for him/does for me. I get a beautiful midrange.

The dream would be for him to try an amp out and see for himself. The reality is, that's going to be tough. So, short of that, you gather as much info as you can and make the best decision.

How loud is probably the most important factor. With the 87 db spec, you will not get 107 db out of any 300b single ended amp. On the other hand, you can you can get 77 db with 1/10th of a watt, 67 db with 1/100th of a watt. Ever hear how loud 67 or 77 db is? Not so loud for some, enough for others. (Factor in listening distances and the size of the room).

So again, in a 300b/GH pairing, I say "it could" work. Depends on how loud and the quality of the amp.

Where is my award? I want my award! ;-)

Onemug,
That was a very good post. I agree with the COULD work given the OP stating his listening level is modest and he sits only 8 feet away. Eight quaility watts may very well be enough, with a revealing system 65-80db is plenty of volume.

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.
