"Listing products no longer made and out of stock. They take the order anyway and then do not notify you that the item is not in stock. When I eventually contacted them after several weeks to understand why I had not received the item they tried to sell me something else. They did refund my money when they saw this review so I've revised it from one star to two."
"I've been buying new and NOS tubes for about fifteen years from almost all the vendors currently in business and overall my experiences have been good with one exception; Upscale Audio.
I bought six gold grade Matsushita 7DJ8 tubes from Upscale, graded A for both noise and microphonics for my Herron VTSP-3A line stage. Five out of the six were noisy and one was so microphonic that speaking at normal levels would set it off. The day after I received them I contacted Upscale using their website messaging system (the unanswered message is still there) requesting an exchange or possible upgrade to platinum grade if those would be quieter. I received no response. Two days later I emailed them with the same request. No reply. I then requested a RA so I could return them for a refund. No reply. A week later I filed a dispute with Visa. Upscale is fighting it.
I've heard similar stories. There are many good tube vendors out there so I would recommend any others before considering Upscale Audio. In addition, I think their tube descriptions and superior testing claims are generally exaggerated."
