“instantly slightly better sound. More precision without brightness. Replaced the original equipment on Prima Luna Dialogue HP. Original was totally fine. I rolled the power tubes and the improvement on the pre amp tubes was more significant. Satisfied.”

“I've just listened for a few hours on my rogue sphinx v3, but I liked these a lot. They were replacing some mullards that were finally giving up (noisy, losing top and bottom) after 8 years of use. These have outstanding base and highs, and nice imaging. They are also very quiet. If they last as long as the mullards did, I'll be a happy camper.”

“After around 20 hr of burn-in I started noticing improvements. Now I have over 100 hr and WOW. Notes and voices have more inner detail, note decay is delicious. Music is more real, instruments and vocals have a more physical position in space. My soundstage is so wide on certain material that it seems there are another pair of speakers at the outer boundaries. I purchased the platinum grade per Kevin's recommendation and am not looking back. Thanks Kevin and your right again, these tubes ARE bitchin.”

“A little too bright for me and my beryllium tweeters. Bass was nice however.”

“2 of these tubes replaced the stock JJ's in my Rogue Audio Hydra. Big change, soundstage opened and detail improved. Very happy with these tubes.”

“Replaced 2 stock PL tubes in my Prologue Prem. Integrated. Great improvement. Better nuance, voices, bass, pretty much better everything. Best $80 I’ve spent. Previous tube rolls were subtle. This is pretty dramatic. All in a good way. The typical Upscale service was just the icing. Just as Kevin has said, Highly recommended.”
