“Purchased a Silver Evo 300 one year ago and It’s driving Klipsch LaScala’s. PLENTY of power, volume knob hardly ever gets past the 10:00 position, music emerges from a super quiet background with great separation and soundstage, classical jazz rock no problem. After a few months I did roll in some NOS RCA clear tops for drivers and NOS Mullards in the gain spot with 1960’s era Amperex EL34’s and got a huge overall gain, especially in the top and midrange, detailed warm, clean and clear nowhere near to bright. Was using the amp so much I got worried about wearing out the Amperex EL34’s So I rolled in a quad of mid 90’s Svetlana Winged C 6550’s that I took out of another amp years ago because I thought they were spent (I remember watching an upscale video with Kevin saying “do not throw away tubes, even if you think they are spent” he’s right). Moved the bias switch to high and I think now I will run this set up until I get a red light. Still have the great mids and highs with the 6550’s but the bass is much better, quicker punchier deeper. Never had an amp with a remote control, it is so nice and this remote is built like a tank. Added a HF Rose RS250 streamer and being able to control them both from your chair is awesome, not the best for your health but awesome. I’m Extremely happy with this amp and all interactions with Upscale have been positive, great people to work with. Thanks Sean Paul, Frank, even got to talk to Kevin once.”

“PrimaLuna EVO 300 Tube Integrated Amp Silver The tonal richness of the midtones is perfect for Jazz, especially horns, great bass response too. I've bought a lot of hand made tube and expensive brand amps and PrimaLuna beats them all IMO from the numerous A/B listening tests I've done. I'm also a big headphones guy, I'm not exaggerating when I say this amp has the best headphone amp I've ever heard, after buying this and the Evo 100 Integrated as I have two setups. I sold my other two headphones amps, one of them being a big brand dedicated headphone amp retailing at $4k, the Evo blew it out of the water, no contest. IMO from all the features it offers, PrimaLuna represents the definitive modern tube amp.”

“What can I say that hasn’t been said. It’s a fantastic integrated. Paired with a Manley Chinook it’s tubes everywhere. I’m surprised by the sound. This does not have to be cranked up to be great. Honestly my dial rarely goes past the 9 o’clock point. A little bit goes a long way with this. I am certain this is my forever amp.”

“I upgraded from a Primaluna EVO 100 integrated (my first foray into tubes), which showed me that tubes are not burdensome to live with, and it’s soundstaging and handling of the bass, midrange and treble, was more enjoyable than my (high quality) solid state setups previously. It’s all part of a chain of equipment though, and once I upgraded to the 300 (I thought the 400 would be too many tubes to live with/roll) I found it was loads more revealing and resolving (read finds weaknesses elsewhere)! It drives my focal 936’s with ease (as did the 100). It shows me differences more easily with any equipment and accessory tweaks. Alas, everything matters! I upgraded my DAC, and Phono pre-amp as well, and added much more isolation to all my components (voodoo cable iso-pods, Stillpoints ultra minis, symposium acoustics segue for my TT). Big difference using Stillpoints ultra minis under my EVO300 (more refinement, blacker & more quiet backgrounds, more balanced sound, and now I can crank it up when I want more impact without harshness creeping in, in my treated room). It showed more subtle improvement with a power chord (tried many but settled on shunyata delta v2 - more refined sound, slightly less overall hiss close up to the speaker). Rolled GE NOS 12AU7’s for the 2 gain tubes (not much difference trying more of these in the driver tubes). In my system an Audience AR6-TS power conditioner makes all the difference with dynamics and soundstage dimensionality with all my equipment plugged into it. Enough rambling, I think the EV0 300 is my end game amp - and great enough to build an entire system around. Nowadays, when I get the urge to upgrade after reading a gushing review, I go back and read reviews of my current equipment - hey what do you know - equally gushing reviews, and often a nugget of wisdom to be found in it about setup and use to squeeze the best out of it. Also, it’s never about a single piece of equipment, but about an entire system and finding synergy within that combination. Happy listening!”

“Driving a pair of Klipshorns with this amp. Out of the box, the PrimaLuna EVO 300 was a bit harsh (if that's the right word), but after a few hours running in, it sounded very nice. After maybe 100 hours, I swapped the tubes to RCA cleartop 12AU7 and Winged C EL34's; now this amp really sings. It has great detail and a clean sound. FWIW, I listen to a lot of (50's) jazz, blues, some rock...the occasional classical album. I cannot turn the volume up past 1/3 and stay in the same room as the speakers. Being able to switch between triode and ultralinear is nice- it is a different enough sound to support jazz vs rock. I 'upgraded' from a PrimaLuna Dialog 2 and this one does sound more musical to me. Is it 10X better? No, but is better, and has some additional features (headphone/sub out) that I appreciate for the future, even if I am not using them now. The EVO 300 is family friendly- remember the old days of telling your kid 'hey kid, adjust the volume', or 'hey kid, change to input 2'. Well, no more of that with the remote! Convenience whether you have a 'hey kid' or not. The phono stage just works. It is simple, no switches, no wires, it doesn't get in the way and that is the best compliment I could give it. As I mentioned- I had previously owned a PL Dialog 2. In ten years, that amp never hissed, popped, showed any signs of dust in the controls or burned out a tube. It was as reliable as gravity. I expect this one to be as reliable. It is nice to have a remote and a well-built one at that. The remote is a machined case, so it is heavy! This integrated amp is also seriously hefty- there is a lot of metal in the cabinet. All the controls have a quality, precision feel. I'm completely satisfied- this integrated does everything I could ask and does it well. It is fairly priced, and the folks at Upscale Audio deserve a big thumb's up for their excellent knowledge, communication and service. This is the second PL that I have bought from them and it is nice to work with skilled professionals.”
