“I run my Evo 400 via a Don Sachs model 2 preamp. They sound glorious driving my new Tannoy Turnberry GRs. Lots of effortless bass…the sort of bass that’s soft yet authoritative. I bought my Evo 400 in 2020 but am only writing this now because I had some reservations about this amp. Turns out it wasn’t the Evo 400…it was my Salk Songtowers. They were great sounding speakers but there was just a little resolution missing on certain tracks that I’m very familiar with. I assumed it was the amplifier. So my strategy was to get the Tannoys and then look for a better amp. Well I’m glad to say that Primaluna and Tannoy are a great pairing and the Evo 400 is staying. I’m getting rich timbre and texture with this combination. The Primaluna sound signature is on the sweet side while the Tannoy are a bit dry. Together, they really balance each other out kind of perfectly. The Tannoy/Primaluna match has already been established but I’m here to say that it’s, at best, an understatement! So very happy with this amp.”

“All my electronics have been tubes since around 1970. I have multiple listening areas with lots of vintage stuff. I am using this EVO 400 power amp to compliment my EVO 400 preamp I recently bought. I was using a Mac 275 to drive a pair of vintage Klipsch Chorus ll’s. The new EVO took around 200 hours to calm down from being way too bright & edgy. It is a more upfront & detailed, & clearer amp then my Mac. However on some horns it’s still a little too bright & edgy at 300 hours. The Mac just softens everything. On most songs I listen to I just love the EVO. Can I live with it is the question or can I live without it! The jury is still out. Lol I listen every day now for hours. I think the solution to some harshness on some cuts is to listen more in triode mode.”

“Perfect. Don't know you get better than this unless you get a Kevin system. Which has elephants turning a generator powering 10 amps built by fairies with boots. I put in KT-88s and have upscales' Wrinkled Glass Mullards up front. P.S. - tell Kevin to stop making fairies wear boots”

“Let me say this simply. The Primaluna EVO 400 power amplifier is the real deal. Seriously no BS it's a end game component. Forget specs and hand waving it's proof is in the performance. After going through many amplifiers over the years I finally have the magic and emotional connection with music again. I will be purchasing a second EVO 400 power amplifier and the EVO 400 pre amplifier in the near future. Build quality is second to none and the fact it's jam packed with high quality parts, point to point wiring and not a empty box makes me rest easy that I got great value for my money. Sincere thank you to Kevin Deal for his informative and entertaining videos that introduced me to such a fine product line. Highly recommended!”

“I would like to thank Ash at Upscale Audio for talking me into purchasing a second EVO400 power amp. Never imagined running both amps in mono mode would make such a difference. Channel separation and dynamic slam has improved substantially. Have to say that having the best of PrimaLuna (EVO400 preamp with upgraded tubes) and a pair of EVO400 amps hits the sweet spot.”
