Sonus Faber Guarneri Homage and Single Ended Triod

Hi Rchan, I would be interested in this answer as well. However, i seriously doubt that any 300 B amp could drive the fairly inefficient GH's.
The GH's like a minimum of 50 watts/ch and come alive with 200+ watts/ch
IMHO. Which 300B amp are you considering?

Hi Rchan,
I would be interested in the Jadis 300b amps and probably
the Air Tight 845's ( single ended but not 300B's) and the Air Tight 300's.
Like you say the Wavac's and the Cary's are contenders as well. BUT, like
I said, I doubt any of them would be a fit for the GH's.
The GH's are so revealing that I am pretty sure that the single ended
amps would be easily heard distorting once they began to get overdriven.
Nonetheless, i am curious, like you, as to this match-up.

Onemug, please tell us what amps you are referring to when you say 'a couple of
300 b SET's'?
Are you using one 300b amp per channel? Not sure what you mean.
In my very small room, I listen at low volume levels generally anyway, so
maybe a 300b might be an option. Although, unless I am mistaken, most
300b's can only put out about 15 watts/ch or less. Do you hear the clipping that must be occurring even at low levels given how inefficient the GH's are?

Hi Onemug, I see what you are saying about the level required for the 10th of
a watt. However, I am not so sure that on bass transients etc. that the speaker
doesn't draw more juice ( Possibly a lot more). Currently, I use a 250 watt/ch amp and amazingly
in my small room that unit gets warm and seems to be working a little even at
lower levels.
BTW, I think the Art Audio amps are very fine. Definitely on my short list to try, along with the other amps mentioned.
There used to be an old a'phile saying... with 15watts you can fill a church.( Problem was with what?) ..:0)

I wander if anyone else has any experience driving relatively inefficient speakers with low powered 300B amps? Thoughts?

Poorguy, do you have any idea how efficient the B&W S805 is?
The Sonus Faber GH's are pretty inefficient, on the order of 84- 86db
I believe.
I would suspect that any speaker below 89db efficiency may not be a
very good match for low powered single ended tubes.
These amps may drive a lower efficiency speaker but I would suspect
would run out of steam very quickly on bass transients etc.
I am curious if anyone has any long term experience with this
apparent mis-match( low powered single ended amps matched up with lower efficiency speakers)( Onemug do you still use 300b's to drive your GH's?) I still want to try this combo myself, so far no opportunity.:0(

Well guys, i have decided to try a vintage ARC D-70 with the GH's.
Not sure on how this combo will play out, but will soon find out.
Will also try a 300B amp as well, if I can get my hands on one.

Cary 805 AE's will probably be a GREAT match for the GH's. Please post your findings once you have a chance to hear them.
