I use these in the 2 middle locations in my Prima Luna EVO 400. They are such an improvement I ordered a small stash as back up.

Second pair. Loved the last ones but they started getting noisy after a few years.

This tube raised the level of my amp’s sound remarkably. Tonality and detail vastly improved.

Gorgeous, balanced sound in the preamp position of my Rogue Cronus Dark. Replaced the stock Psvane Art series which is no slouch in its own right. This added just a little more presence in the midrange to make voices shimmer a little more :) Great service from Kevin & Co. In replacing a defective tube - you guys rock!

I placed these tubes in the front end of my Prima Luna EVO 400 integrated. I believe the sound is better. Everything sounds really tight and I think the mid range is vastly improved. Great upgrade to an already great amp.

By now I’m never skeptical of Upscale Audio , recommendations, over the years they have been stellar. So when I found out that Kevin’s private tube collection was available, I immediately made my order. I expected a subtle difference from my PrimaLuna Evo 400 Integrated Amp . Totally shocked that it was subtle at all , basically the Brimar tubes significantly defined the mid range causing the high and lows to sound tighter, a truly audible three dimensional soundstage . Once again , no bill , no selling / marketing blah , instead, let the product speak for itself . Strongly recommend those on the fence line , buy now before their gone . There’s a reason why Kevin has been hoarding these tubes and is so reluctantly sharing them now . Thank you guys …AL .
