Jim McShane, Brent Jesse, Andy Bowman, Brendan Biever and Doug's Tubes are all great tube vendors. I've also had good luck with larger vendors like Tube Depot. I would never recommend Upscale Audio. My experience with them has been terrible. Others have had problems with Upscale as well.
Not only will you get bad tubes from Upscale but it's likely the service will be even worse. With all the good tube vendors mentioned above, there is no reason to consider Upscale.
