Tubes were shipped and arrived quickly. They sound excellent. I also appreciate the follow-up that Upscale Audio does as well as the fact that their personnel does not work on a commission basis. I never have had the feeling of being "upsold by Upscale." :)

My favorite power tube by far. It has all the attributes of the EL34 plus wonderful soundstage, great bass, more space between instruments. Voices more upfront. More notes, more music! Super fast free shipping just can’t be beat.

Haven’t had the KT77/EL34’s long enough to truly give them a proper elevation, but I like what I’ve heard so far. That brings up a question, I have a Primaluna Evolution 300, do I run it in high bais, or low? I’ve tried both, and there’s seem to be no difference. Thanks in advance for your expertise.

Hi RP Martin, The KT77 tube should be run in the LOW setting just like the EL34tube. This will preserve the tube's life.
