Avantgarde Trios too loud with my amps

It's not the amount of power, it's the gain structure of your system when listening to your digital source. Contact BAT about lowering the preamp's gain. Alternatively, SMC makes a device that reduces system gain by 12dB that works in either balanced or single ended systems. You could insert it before your preamp.

Onhwy61,
I agree that system gain reduction is certainly a viable choice(especially if he wants to keep the BAT components).

If he`s interested in exploring a 'different'type' of sound and musical perspective with lower power SET amps,he has the ideal speaker to take advantage of their special qualities.These speakers provide significant flexibility.

Ohhwy61,
Come on man, those were my words! I wanted to say it first- not fair.
Of course, the power of your amps has nothing to do with the loudness, it is a gain structure of both- preamp and power amp.
I have Avantgarde speakers, and know exactly, what you mean.
I was also told, that it's better to have lower gain in the preamp, than in the power amp.
Attenuators are an option, but will come with some, maybe negligible, degradation of signal.
But, a reduction of your system gain will afford you immense benefits- much lower level of background noise, more precise volume control, etc.
Please, do yourself a favor and contact Victor Khomenko of BAT, maybe they will be able to reduce gain in your preamp- you will benefit also from having less connections in the system (b/w attenuator and amp/preamp)
As a matter of fact, Victor has Avantgarde Trio and (surprise, surprise) BAT electronics in his personal system, so he should know how to help you
Cheers

Agreed re gain, not power of amp, but the Lamm SET/AvG combo is
special in my experience. (And yes, I have used other amps with the AvG
as well). A pair of used ML 2.1 are probably in the neighborhood of 13k
dollars US from an authorized dealer, and well worth comparing if the OP is
going to the trouble of getting the most out of the speaker/amp combo.
Like I said, I rarely recommend components I use. Interesting to note that
several other AvG owners who have posted here (Triode, Maril) have the
Lamm
and the other poster-Chadeffect- who also owns the Trio, recommended
similar types
of low powered tube amps.

Yes,you can have excess gain with low power amps in the system also,no arguement.It would be fun (if possible) to try different low power DHT SET as they all have their own attributes.Chadeffect`s amplifier odyssey is quite interesting and informative.I can imagine the pure beauty of his 2 watt Yamamoto driving these speakers.It`d also be interesting to hear the very different Lamm for another sonic approach.
