“Tubes are very quiet, work great in the original model Freya preamp. Shipping was very fast. Thanks!”

“These tubes are quiet! I have four in my Schiit Freya preamp and can hear no hiss through my headphones. I have only NOS unnamed tubes to compare them against, so I cannot say how they compare to other branded tubes.”

“My NOS tubes had become too noisy and I did not want to pay a premium for similar NOS. I watched videos with Keving discussing tubes and liked what I heard. I ordered the platinum with cryo. Upon initial installation, the tubes were dead quiet but seemed a bit bright and lacked the bloom of the NOS. After burning in for about 70 hours, the sound mellowed and I am now hearing much more detail in my system without any fatigue whatsoever. Additionally, I had a question when I was placing the order and a phone call to Upscale proved pleasant and informative. I will definitely be purchasing my power tubes in the near future from Kevin and company.”

“Unfortunately after I ordered this tube, I changed my mind about the amp I was going to get. Now I need a pair of 12au7s instead of the Tung Sol I got from you. I guess I'm stuck. But thanks for your enquiry.”
