“I’ve purchased a total of eighteen Gold Lion KT88’s in the last 16 months. All 6 purchased from Upscale are still running strong. ONE HALF of the other 12 purchased elsewhere have already faulted. I’ve never had any issues with tubes from Upscale. Compared to other tube vendors I’ve learned the hard way, can’t get the same kudos from me.”

“I love the sound of these tubes. Running in two Primaluna EVO 100's, used to bi-amp B&W speakers. The sound is more muscular than the stock EL-34s, with a more defined and "slammy" bass, without losing too much on the top end. However, I bought a set of 9 tubes in July 2022 (one spare), and now in Dec 2022, with under 500 hours on the tubes, two of them have gone bad (in two different sockets on one amp). I'm wondering if Genalex are having quality control issues.”

“For modern production power tubes, the Gold Lion KT88 is a really nice addition to any amplifier. Upscale Audio provided top-notch service and support, and was incredibly responsive. Fast shipping. Could not be more pleased. Thanks all!”
