“I do like the Gold Lion KT88 Cryo treated valves. Without going on about details, the last purchace Was for Spares. Ive yet to open them. I trust Upscale Audio, and dont feel the need to run the spares for 30 days to "test under warranty". Maybe i should, but im not this time. Thanks Upscale Audio! -Mark”

“Lovely wonderful sound. A keeper. Took me a while to get there. At first a clangy piano and bloated bass. After many hours including a few overnights improved but still not fully clear or enjoyable. I went to some EL34s I keep for back up for a while and they sounded quite nice. Considering the glowing reviews I wondered if something else was amiss. (My system: EVO 300 Integrated, DH Labs, Cheviot.) It was the small signal tubes! With a set of new GL12AU7s the KT88s sounded very nice although slightly punchier than what I was used to. The bass was slightly exaggerated for my taste, note that I play double bass. However after a few more hours the bass was well balanced. That the KT88s showed a weakness in the year and a half old stock tubes is notable. Perhaps the larger current draw has something to do with this. After realizing the drivers were weak curiosity demanded I revisit tubes on hand. KT66, not as “analytical” as previously thought. Overall very nice. KT77, wonderful! Almost a 3D presentation, especially voices. Easily the most pleasurable to listen to in my system. My reason for trying other varieties is the known reliability problem with the GLKT77s. Of the tubes I have tried so far KT88 is an extremely close second. It is very good and the music is almost as beautiful as the KT77. I listen to mostly classical and also vintage jazz with a little classic rock”
