“Sounds wonderful but 1 tube had a "popping" sound with volume adjustments. After texting about problem sent tube back and got a replacement with no issues. Back in audio nirvana and thanks to Upscale for making everything so easy and fun. Cryo tubes seem to have more depth and increased soundstage compared to my previous matched Gold Lions.”

“Not sure why but my Primaluna Hp Integrated had a bit of a harsh top end with stock tubes. I've owned two other Primaluna amps that didn't have this. I replaced the pre-amp tubes (two at at a time) with Gold Lion. I got these Kevin's Stash for the front two. It made a difference! Much sweeter sound. Also have to add I've had great customer service with Upscale Audio.”

“I recently purchased 4 Kevin's Stash pre-amp tubes. All are excellent & I've been enjoying some tube rolling in my Vincent PHO701! Excellent products & service, as usual.”

“Bought these after reading glowing reviews on the PS Audio community board. Couldn't be happier. Great step up for my PS Audio BHK preamp.”

“I purchased the Gold Lion 12AU7 Cryo-treated pre-amp tube for my Primaluna Premium Dialogue HP amp and was surprised in the upgraded sound. I could tell within the first few notes of Pat Metheny Group "Imaginary Day" DVD Audio in stereo. I sat and listened to the whole album from start and finish. Amazing sound, everything tighten up. I do like a good bass line. I went through LP's and SACD's all with the same results. I am a happy customer and strongly recommend Kevin's Stash/Cryo tubes. It is worth the extra cost. I ended up replacing the tubes in my pre-amp as well with Kevin's Stash/Cryo. HIGHLY RECOMMENDED!!!!! 5 STARS***** out of 5 Stars*****!!!!!”

“The Gold Lion's replaced a pair of psvane tubes that were always a little noisy and sterile sounding. The improvement was nothing short of breathtaking the glorious sounds that came from my Triton 1.r was just so good.”

“The gold lion tubes were a good buy for me. And never hurts to have some extra tubes around. Upscale Audio is the only place I buy tubes.”
