“I had tried some NOS sylvania tubes off eBay and they were ok until I got a set of 98db speakers. I was hearing noticeable buzzing. Since replacing the Ebay tubes the problem has been mitigated. I’ll just get all my tubes here now.”

“Wanted to try a tube preamp for some time to see what a difference it would make. After reading quite a bit on different amps, and their reviews I decided on the PrimaLuna Evo, 300 tube preamplifier. Even though I had no way of listening to it before I purchased it, and it's cost was quite expensive to me. I thought if I don't like it, I can return it. Well, it was shipped quick quickly and as you've probably already read, it was packaged extremely well. Got it out and hooked it up to my system and I must admit I heard a very noticeable difference right from the beginning. Everything I had heard about and hoped for was there. Especially the separation of instruments and vocals, and not only a wide soundstage but a deep one also. The very highs of my existing system could be a little tiring for me and I hoped this would also change that. It did without eliminating the highs. I still get beautiful highs but have eliminated what I'll call a screechyness about it. Of course, my subwoofer no longer was powered so I sent an email asking if I could plug my subwoofer into the other output of the preamp. I received a quick response stating that I could. Sounds great. After just two or three weeks I had a tube go bad making a very loud hum. Again, I sent an email explaining my problem to upscale audio. To my amazement within just a few minutes, I received a phone call from them to resolve the problem. Which they did and very quickly. Yes, it was a lot of money, but there is no way I would return this preamp. Very happy with everything. Not only the quality of the prima Luna and the sound I am getting from it but also the service I have received from Upscale Audio.”
