“These were recommended during a conversation with Upscale. I had been using Wing "C" 6550 but wanted a bit more bass but I wanted to keep the lushness of the 6550's. Well, many years later I still using the GL-KT88's. Once in a moment of cheapness, I purchased a few replacements from a Amazon based tube vender, bad move. Of the four tubes, 3 failed within 4 month. I've never had a failure rate with Upscale product. I have been using these folks since 1999, great product and outstanding customer service.”

“I agree with everything Kevin said about these tubes in the video as well as many of the commenters. They are clear and detailed throughout all frequencies - strong bass, clear & liquid midrange, extended highs (which balance out the top-end softness in Tannoy Revolution XT-8F speakers)”

“A little more punch in the low end then the EL34s I was using before. Very happy with the performance.”

“Love the KT88s in my integrated Primaluna Prologue Two. Much more dynamic than my Mullard EL34s with my Magnepan LSRs. I wasn’t sure if this tube amp had the oomph for LSRs but it has been a month and I still haven’t rehooked up the solid state amp with tube pre. Sweet KT88s”

“I bought these to replace a set of 6550s in an old tube amp I inherited. Everything you've read about these tubes is true. They sound fantastic. I'm listening to Buddy Guy right now. I feel like Upscale Audio really takes the time to match them on tubezilla. I have a bias meter on the amp and they are solid as a rock.”
