“I am using these in my Freya+ preamp. These tubes are ultra quiet, with deep bass, accurate mids and balanced "airy" highs. I am using high efficient loudspeakers and I cannot hear any hum, noise or harshness. I am very happy with the sound coloration mostly due to the depth and soundstage and clean sound. So far I have 500 hours on these tubes.”

Thanks for this useful review, Ash. And the 5-stars are greatly appreciated. A lot of people think that the Schiit preamps don't respond much to tube-rolling, but many customers have had great improvements with different tubes.

“Tasty-Tubage yet again from Kevin Deal and the Upscale Audio Gang!! I bought them for a Schiit Freya+ Preamp and they sound GREAT! The J.J.'s that come standard with the Freya+ were/ are fine enough sounding tubes but there is just something special about an Upscale Audio Cryoed tube!! The bonus is when they come from Kevin's Stash!! Thanks again - Dana”

Tasty-Tubage... we like! Yes, Kevin's Stash are really special tubes, and there's very few of them in each batch that make that grade. Hold on to those!
