“My Rogue Audio Sphinx V3 sounds light years better—this is a no brainer upgrade. Compared to the performance of stock tubes, amp sounds like something easily worth 1000USD more (at least that’s how much I would’ve paid if the dealer did blind back to back and told me the upgraded tubes was actually a different amp, one model up). I don’t know if everyone’s experience will be the same, but this is certainly mine.”

“I wanted to get the most from my LSA VT70 Tube Amplifier, I did some research and decided to go with the Mullard 12AU7 /ECC82. This tube is the most smooth and holographic tube that I have come across. The sound has a slightly laid back however crisp detailed top end that is very non-fatiguing and a liquid midrange that is very pleasing. I like them better than my NOS ECC82 Amprex Bugleboy's and that says a lot. Very satisfied customer. I will shop again.”

“These Mullard 12AU7s replaced the PL stock gain tubes in my Primaluna EVO 300 integrated amp. The tubes sound great. Only a relatively short burn-in period was required - 2 weeks of casual listening. The PL stock tubes also sound very good - I was looking for a reasonably priced tube to try some tube rolling just for the fun of it. Upscale processed the order really fast. Very satisfied.”
