Sonus Faber Guarneri Homage and Single Ended Triod

I own a pair of the GH's and have driven them with a couple 300b SET's. It is not my usual pairing but it works for me because I enjoy low and medium volume levels.

I think you should try it, assuming you are not a headbanger. I love the 300b and the single ended sound is something I think everyone in our hobby should at least try once in their lifetime. It may not be for everyone and it requires a compatable speaker but once I heard it I was hooked.

BTW, I have a lot of respect for Cary amps. I own their Rocket 88 and V12i that I use on my Maggies. They are push pull but have a triode switch so I'm half way there (triode but not single ended). In that case I need the extra horsepower.

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?

Daveyf,
I only used one amp at a time, never biamped. The best one was the Art Audio Symphony II. It puts out 10 wpc, has a great power supply and transformers which all help contribute to the sound. I have not heard any clipping.

Food for thought: Average convesation is around 65 db. Averarge factory levels are 75 db. You get 86 db with "1" watt from the GH's at 1 meter. Even accounting for some variables, if you listen at "factory level" you may only be using a tenth of a watt.

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)

Daveyf,
Yes, no doubt those bass transients are going to want some power. I read once that transients can take up to 200 times the rms power to reproduce them. 200 times a 1/10 of a watt = 20 watts, beyond the scope of most 300b SET's. One rms "bell" louder and you'll need 200 watts, so you can run out of power real quick if you like to crank it. Transients are of such short duration that an amp with a strong power supply might pull it off to some degree.

When ss clips it's usually not pretty, pp tube is better but triodes clip pretty easy on the ears.

I'm experiencing that with my Cary V12i's and Maggie combo. This Cary is 100 wpc ultralinear and 50 triode. Triode sounds more powerful. Go figure. BTW, the Cary has el34's which are not triodes. There is a UL/Triode switch that changes the operation.
