“This is my 2nd purchase for this tube from Upscale (Kevin's stash/cryo), and I just love this tube and what it does for the Audible Illusions L2 Linestage. I've used NOS Telefunken (also great); but I love this tube, not "just for the price," but because of how they sound. It's a terrific tube at any price.”

“Thank you again for letting me know a 7DJ8 will work in place of a 6DJ8. The sonics of this tube are impeccable, as long as you're not looking for the sound of a Mullard. This tube is all about clarity and dynamics across the spectrum. It made my inexpensive headphone amp sound great!! Thanks again”

“Using a set of 3 in my EAR 859 and they are simply, magical! I have been buying tubes from Upscale Audio for over 10 years and they never disappoint.”

“These National 7DJ8 tubes added great detail to my MW PH9.0 phono stage. Stock tubes were overly warm. Also tightened the bass and added air to the top end. I'm very happy with this purchase as I have been with all previous purchases from Upscale..Kevin definitely knows his tubes...”

“The Beauty of the Feliks audio echo is the 6922's have equivalent or better tubes and the National pcc88 are just what was described by Kevin.”
