Big improvement over the Evo 300 integrated which is what I initially started with when experimenting with PrimaLuna. Currently using Phillips 5R4GYS rectifier tubes with reissued Russian Mullard 12AU7s in the front 2 sockets. Definitely rounds off the edges for a very euphonic sound without sounding too warm or syrupy. Not the last word in detail and resolution but with the Naim NDX2 as a source it is an exceptional blend of detail, rhythm, and holographic staging of the stereo image.
PrimaLuna Evo 300 Monoblocks
Running 2 Evo 300 amps in Mono mode with 4 Tung-Sol KT150 power tubes in each, as well as 2 NOS Brimar CV4003/12AU7s in the preamp sockets. The KT150s add exceptional weight and body to instruments and voices, particularly guitar strings, piano notes, etc. They exert grip and control over the bottom end while still maintaining the silky and forward mids and top end of the EL34 tubes. Combined with the Brimar CV4003 tubes, this offers a uniquely euphonic sound with tight, detailed bass and realistic weight and timbre that is not harsh in any way - in fact more velvety-smooth on mids and top end. A very engaging combination.

@tablejockey for sure... I want to get some full-range GIK 244 panels up there. However I just got done waiting 3 months for my most recent GIK order so I'm going to wait until things open up a bit hopefully by summer and then that would be the last piece of the treatment puzzle.
@thosb thanks, it does sound awesome. Regarding panel placement, I already had the 7" Monster bass traps against that front wall because my home theater is on the other side of the room. To counter that I knew I'd want some diffusion up front (there are 9 other absorption panels around the back of the room). As I got to experimenting and listening I also came up with the visual idea of staggering the height of the diffusion panels both for effectiveness but also for the interesting visual impact of the panels.
