“Once again Uncle Kevvy comes through! Bought a used PrimaLuna Dialogue HP integrated amp. The amp sounded great, but I wondered if I could get more. Between watching the videos on YouTube and reading the reviews, I decided to upgrade the preamp tubes. Well things got more focused, with more weight to all the instruments. You could tell when a drummer was using brushes and how tight the heads on the drums were. The Brimars are good news bad news. The bad news is I can’t see myself doing anymore upgrades anytime soon, unless I get a pair of Kantas, then I will upgrade to some K120s!!!”

“I bought two of these for my Evo 400 preamp and they made a difference right out of the box despite (or because of) being the same age as me! Better imaging, more open sound stage and good bass impact. The whole presentation is more holographic. Very glad I made the purchase. It has improved what was already a great sounding amp. As usual, delivery from Upscale was prompt and the tubes arrived in perfect condition. Thanks Kevin.”

“Pricey for small preamp tubes but audiophiles spend 5-10 times as much on cables and probably gain less performance than these tubes provide”

“First of all I would like to thank Upscale for consistently providing top quality tubes. These Brimar 12AU7 tubes have a delicate air to them. They are one of my favorite input tubes for my amp.”
