“I've been uising Tung-Sol tubes for perhaps, 20 yrs. now. They always sound good. Installed and worked fine. No defective tubes at this point. Haven't broken in yet. Maybe 20 or 30 hours so far. Dealing with Upscale's people is a pleasure. Knowledgeable, helpful, and friendly.”

“Sound great. Replaced some EL34 tubes in my Black Ice Audio F22 amp.-- Sounds much better for my kind of old guy rock and techno music from 70s and 80s :)”

“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”
