“I have introduced Furu-Tech's top of the line NANO iec connectors on my Cullen Crossover main incoming power cable going into my Furman Power Conditioner and just recently , I coated other power cords, interconnects, as well as my Kimber Kable 8TC Speaker cables with Furu-tech's NANO Fluid. The Tung-Sol 6550 power tube with your Cryo Tx. sounded fine in the V1 position on my Black Ice F-22 Tube amp initially, but after adding the Furu-Tech upgrades, the whole system makes my Heresy III Speakers sing with a sound stage that is very open, airy , precise and extended, and overall, it sounds just plain beautiful ! By the way, I will still be interested in purchasing a set of 4 Genelex Gold Lion KT-88 Power Tubes and a set of 4 Gold Lion AX-7 pre-amp tubes from you in the future. But for now, the replacement 6550 Cryo treated tube you sent me has blended well with the other 3 6550 power tubes and my system sounds great. THANK YOU from this well seasoned retired audiophile in Vermont, Illinois. Randall S. Wilson”

“Outstanding in my ARC 40th Anniversary Reference power supply. Two of these do provide a dead quiet steady image. Sonically, transparent, and sweet. Very, very close to my NOS three hole gray plates.”

“Used the new T-S to replace a blown 1970s vintage Philips. The sound was bright, clear and responsive right out of the box in my CJ amplifier. This is good quality that’ll improve as it burns it more. Thanks”

“Great power tube for the Doge 10 integrated amp. Huge soundstage with hefty bottom end, smooth mids, and articulate highs. Great tubes and great service from Upscale.”
