Testimonials

"I think it's a great sounding piece or more accurately, non-sounding, in that is doesn't seem to leave a sonic footprint."

"The sound is absolutely fantastic. Was using a step-up transformer and the Piccolo eliminated the hum that was driving me nuts. I am spinning vinyl almost exclusively now."

"The increase in dynamics and soundstaging I expected are there in spades! HUGE!"
