“These replaced the stock J&J ‘s in my Rogue RP-1 preamp and they accomplished what I was hoping for. On some lp’s horns were too bright, no longer the case. I also want to compliment the Upscale Audio staff. When the tubes arrived I overlooked where it said they were cryo treated. It was right on the store label. They were quick to refund the difference but I later caught my error and repaid the amount. Would not hesitate to do business with them again.”
