“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.”

“Yeah it’s like I upgraded my whole system really amazing every single thing got better from top to bottom - front to back and detail beyond - by a lot - more refined deeper bass - warm and luscious tones all around that seem have more hang time and texture than before with the stock Psvane. I used these in the PS Audio M1200 input stage. Didn’t lose any slam or dynamics they may have improved slightly. Fun Times!”
