“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.”

“Used for Primaluna Dialog Premium preamp. The set of 4 GL tubes replaced factory installed PL tubes. One PL tube went south and did not have a choice but to buy new tubes. Fresh from the box I noticed better clarity of the sound, better dynamics and better extension at frequency extremes. After a while I decided to even better that sound. My question to Upscale was simple: do you have any better tubes in terms of better dynamics, clarity and frq. extension. Their answer was also simple: no. Does anyone need better recommendation? Also tried Brimar. Hadn't tried GL tubes, I would've stayed with Brimar. GL sounds crispier, more detailed.”

“I've owned a PrimaLuna Dialogue Premium Integrated amp for almost one year now. I'm amazed how much tube rolling affects the sound, with regard to both the input and output tubes. The unit went from very good, with the stock tubes, to stellar with the KT 120's in the output section with the cryo treated platinum Gold Lions in the input section. The Gold Lion's excel at detail and ambience retrieval, providing significantly more texture with instruments and vocals alike, greater delineation of instruments, a more spacious soundstage, sheer listenability without the slightest bit of glare or listener fatigue and a top to bottom coherence that just begs you to listen for long periods of time. I have not tried the NOS Mullard's or Brimar's yet, but honestly, I'm in no hurry to do so as I can't imagine my system sounding better than it already does. It sounds so good I don't have a sonic wish list, hoping for a little bit more of this or that, like more extension, transparency, dynamics, etc. Instead, I just listen and enjoy what's being played. A bit of info for PrimaLuna owners, just installing 2 of the Gold Lion's in the driver stage had a tremendous impact on the sound, so you don't necessarily need to replace all 6 tubes to dramatically change the sound. However, I did replace all 6, which improved the sound even further.”
