"I would like to say that if someone had upgraded my system components and achieved  the improvements your products produced, I would have felt them justified in charging me thousands of dollars. I feel I am in your debt to have received these benefits at such a modest price."

"AFTER THE FIRST PURCHASE FOR EIGHT FOR EL34 VALVES I WAS SUPRISED AT THE DIFFERENCE THESE MADE.AFTER FITTING THE EIGHTEEN THAT ARRIVED TODAY. I AM STAGGERED. FOR THE FIRST TIME I CAN RUN A PAIR OF PAPWORTH MONOBLOCKS FEEDING THE HF SIDE OF THINGS WITH THE SENSITIVITY CONTROL FLAT OUT WITH NO GLARE OR HARSHNESS AND FEMALE VOCALS AS THEY SHOULD BE. THANKS FOR A PRODUCT THAT WORKS IN A STUNNING WAY, BE BACK SOON FOR SIX MORE FOR FOUR 300BS AND TWO 275B RECTIFIERS."

"Installing Ultrasonic 30 damping instruments on my Atma-Sphere MA-1 mono blocks was equivalent to properly calibrating a good monitor or projector - everything across the board improved and so far I can't hear any negative impacts (like I could in previous versions which used different materials).

"If it makes sense, the notes last longer, yet are faster and have more texture.  The perceived volume also increased since there is a noticeable amount of new detail and clarity."
