Primaluna EVO 300/400 Preamplifier owners - let's hear from you

Yes, I use the original tubes and it is very quiet. I only use the remote which is extremely substantial. The volume adjustments are very incremental allowing a lot of adjustment flexibility. I do have a setting where the volume is a little lower than I prefer whereas the next higher setting is a little too loud. I actually prefer the louder setting.

I like music that has a lot of background information because it is now more noticeable. Eric Clapton, the Band, Grateful Dead, Rush, the Beatles, and a lot of other seventies rock bands. The more detail that is generally indiscernible, the better. I’m noticing sounds that I didn’t notice before. I do think that the build is substantial and even though it has a unique appearance, I like it. You can certainly see a lot of tube presence. 

I have been an Evo 400 preamp owner, for 2 mo's. It is is the best preamp I have ever owned, by a wide margin. I have owned 3 others. I use Shunyata PC's on my amp ( SS class AB) and the evo 400, and my source streamer ( Uses Shunyata black Mamba PC) . I also use an oppo bdp 105 modified by Modwright with a tube circuit. It uses a shunyata sidewinder Gold on the outboard tube power supply, and a PS audio pc on the 105. Speakers are B&W Nautilus 805 signature 805. I have never enjoyed the music more. I used Upscale audio's 60 day trial, and I never sent it back. My ears don't lie to me,  whatever the opinions on theses forums say. 40+ yrs in this hobby listening. 

I have used Single ended and Balaced IC's with my Evo 400. The balanced perform much better in my system..I heard noise with the RCA, that disappears with the Balanced IC's. I am using Shunyata Venom digital RCA, and Shunyata Venom XLR with NAD c 658 streamer source. 
I turn on the Evo 400 with the volume turned off.  Amplifier 1st or Evo 400 1st doesn't seem to matter. The Evo 400 has a timer to let the tubes warm, before allowing the source to connect. 

PrimaLuna offers the best value in audio, they're comparable to ARC.  No I'm not a PrimaLuna dealer, just an owner of their monoblocks since they came out.

With all the things going on in China, that can not last much longer, so I suggest git while the gitten is good.

I've had my Evo 400 preamp now, for about 60 days.  It's paired with a Peachtree Amp500, feeding a pair of GoldenEar Triton 2+

The preamp provides a DEAD QUIET noise floor.  Power-on is a flick of the switch, and about 20 seconds later... you hear a click or two... and see the status light flip from red to green.  I use mine DAILY for several hours.

I'm running it with balanced XLR between the Luna and the Peachtree... no hum... no intermod... and you'd expect no less.  I think the way I'd describe this preamp is: "Neutral, but not cold... and sharp, with a pleasant clarity for the price-class."  Much of that is likely the rest of my audio chain, but that's how I'm perceiving it, when I added it to the loop.

The remote is substantial, but in my case, you just "barely" need to tap on the volume buttons to achieve a bump in change... and if you're heavy handed... you can overshoot quite easily.

The build quality really is top notch.  Nothing to sneeze at there.
