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

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. 

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 invested 1/3 American. 40%  European 20% Chinese and 10% Japanese. After enjoying the music with my wife of 32 years this evening. She said best: The music sounds like a live performance in our home. I can hear the singer's breath! The Chinese built Primaluna evo 400 (Chinese built) and  Shunyata XLR cables (American built) did this. That is why.
