EVO 300 Tube Integrated Amplifier

“Dynamic yet sweet amp!

Rating: 5 out of 5.

I received this amp from FedEx yesterday. This was an upgrade from my Primaluna Prologue premium integrated that I had purchased a couple of weeks ago. I was thoroughly impressed with the Prologue over my previous amp, the Rogue Audio Sphinx. Once I heard the Prologue I had to upgrade to the Evo 300 and see if the increased bandwidth and other improvements would be obvious to my ear. 

Right away I noticed a slightly bigger soundstage and a little more air surrounding the vocals. Their was good definition and slam to the bass. 
The amp was a bit bright out of the box but it started to settle in nicely after only a few hours of play. I really enjoyed the ability to switch back & forth between triode and ultra linear modes. Playing the CD’s/tracks: Eva Cassidy (Live at Blues Alley), John Lee Hooker (I’m just a country boy), and Janis Joplin (Kosmic Blues -Live) in triode mode was a real treat. It brought a lot of texture & emotion to the vocals.

Overall, I am really excited about the upgrade and am looking forward to many long days of music enjoyment in the future. I will be adding a turntable to my system in a couple of months. I am currently waiting for a Border Patrol DAC to add to my Cambridge CXC transport.

Current system: Primaluna Evo 300 integrated amp, Klipsch Forte III speakers, Cambridge Audio 651C cd player, amp & CD power cables by Signal Cable, Audioquest Rocket 44 bi-wire speaker cables (waiting for Mogami W3104), Mogami 2549 analog interconnects.

“Sweet Jesus!!!”

Hi Kevin

Just a quick note to let you know all is good. FedEx dropped the PrimaLuna off about and hour ago- and as luck would have it, my house is in complete disarray from the remodel- but, that didn’t stop me from unboxing this beast, throwing it in my rack and attaching the only source I had handy – a $20 Bluetooth dongle- hooked up the Cheviots – and figured I’d listen to the Sound of Silence by Disturbed …… all I can say is HOLY SHIT!!!!…… the air around the vocals…… the bass I was missing, the sweet melodious sound of tubes…..it’s all there….. Stunned is all I can say. Is possible that this setup is even better the my dialogue pre/hp/Nola set up? I believe so….. this is a fantastic combo….. can’t wait to hear how this sounds after everything fully broken in….

I’m as giddy as a 5-year-old at Christmas. 

Now to go dig my PS audio DAC out and see what this combo can really do…

As always, thanks for the help.
