The cost for a used Art Audio PX-25 should be within the ball park. The s/n ratio, the quietness is astounding, as is the fidelity. Rumored to be Art Audio's finest amp. The quietest amp I've ever hear. Perfect on my Duos. With this amp, you can hear every scrap of music as songs fade out into blackness at the end of a cut. Hearing into the music in that manner really adds to the realism of your listening experience. (Lacking this level of quietness, most other amps/systems cannot capture this low level content.) Note, that your preamp, if it is super sensitive, may be contributing to the inablity to turn up the volume.
You'd be surprised that in many cases, AG's do like power. Though the "little" PX-25 works exceptionally well, able to provide both micro and macro dynamics. And they can boogie too.
