“Bought four Gold Lion KT88s for my Willsenton R8 integrated tube amp. They not only look great, but sound great too. Thanks Uncle Kevin”

“Great service. Web site for upscale helpful in making the correct choice. Not an experienced tube person so I needed every bit of information provided. Concur that reviews are key but would not have been looking in the right place without the excellent videos and background information provided. Have gotten many unsolicited comments about how much better my VPI/Cary system sounds. Awesome experience. Now that I have found you I will be back.”

Hi Jim, Thank you so much for your review, and we're glad to have you as a customer! We put a lot of time into our tube testing, and with power tubes we burn them in for 72 hours and test them while hot for the most consistent results.

“Incredible bass and highs are pleasant. Bought 4, 1 set lasted about 2k hours. Definitely my favorites.”

“Great sounding tube in a refurbished early 1960s MC275. Closest I have heard to Brittish GEC KT88s, of which I have several. These are well balanced, resolving and natural in presentation. Ordered on line and they arrived promptly and securely. Have purchased many tubes here and will continue to do so as needed.”

“Hard to find tubes in 2022 (Ukraine/Russia situation). Glad I ran across Upscale Audio. Tubes were to fix a Hammond Leslie speaker. Tubes arrived extremely fast (two days) and I was able to get the Leslie up and running after soldering in a new fuse and replacing the tubes. Sounds great. Tube were really of great quality.”

“I have changed power tubes twice now from the original KT88 tubes that came with my amp. First time to EL34 Mullard tubes to experiment with EL34,s. Missed the KT88 base. Now with these Gold Lion KT88s, the base is back plus way smoother mids. Not even broken in yet, but they put a smile on my face. Nice!”

“I have been a sound engineer (live) for many years. Music has been a way of life for over 40 yrs. I have a pair of MC60s that I revalved in 1981 with original Genalex Gold Lions. These new reissue Gold Lions I will put up against the originals any day. I received my order promptly and intact. The tubes were matched well. I have a Willsenton R8 integrated amp that I have paired with a pair of Klipsch Heresy IV speakers for my living room, I tired the original GL KT88s (from MC60s) in this amp before ordering. It opened up the sound considerably and made triode mode much more dynamic and controlled. I ordered the reissues and expected them to be bright out of the box, this was not the case. The burn in that upscale does, settles the valves nicely. The sound is better than my originals (probably need to replace). The bottom end is very controlled and not boomy, the mids are very clear and deep, the highs are very sibilant but not harsh, The dynamics make for a very true to life sound that is warm and very enjoyable to listen to. I would recommend this valve to anyone that wants true to life sound from their amp. Thank you Upscale Audio for your dedication to awesome audio.”
