Most beneficial change .

yo'll need bass and weight for that. a bigger reference 3a will do it....the veena will.

If I had a small room the only speakers I would use would be Quads, they are amazing in a small space where you don't need to generate huge SPL's.

room treatment

I didn't audition PrimaLuna, but I had that feeling when I had CJ preamp. The sound had good extension, very smooth, excellent midrange, but it was boring and I could fall asleep while listening. I take it as different people looking for different qualities in component. Some people prefer laid back smooth sound, and others prefer live and dynamic sound. It's a matter of preference, not one is better than the other. VTL preamp that I'm currently using is at the opposite end of the spectrum, alive, dynamic, with toe tapping quality. You might consider switching your amplification.

B 4 I made any major move, and the sound you have now is good, I'd go back and re-examine the tube selection in the Int.

I've found a mix of tubes whose properties are dissimilar in the preamp section, and/or amp section makes a great diff in the involvment of the sound.

Perhaps in de-detailing or smoothing off the rough spots as you alluded too with previous tube rolling, you went a touch too far... or didn't get the combo of tubes just right, and settled.

ON my tube preamp I have smooth NOS RCA on the input (rectifier) side, and and dynamic NOS Amperex Bugle Boys on the output.... on my tube monos I keep the detailed dynamic thing going with NOS Tungsol input tubes, but go to Winged C EL34 on the output sides.

Try some Amperex whites, Tungsols, Sylvania, or some other snappy dynamic tubes in there somewhere but not in place of those which eased up the presentation and see what happens.

Then... look to amps or speakers.... it's easier and cheaper to do tubes first
