PrimaLuna Prologue Premium vs Luxman SQ-N10 ?

@dweller Thanks for the word of caution. I've heard a number of folks saying the unit is dead quiet, so I'm wondering if your unit is defective. Is this hum present on all source selections? And does it sound like a ground hum or tube noise?

@dweller also, what speakers are you using? 

Hey @dweller quick question for you. Is the hum in both channels or just one?

So I got the ProLogue Premium Integrated yesterday. First impressions are overall pretty good, where the musical center is slightly lower than the Luxman SQ-N10, which at 10w feels pointed just slightly higher. The PrimaLuna definitely shows more weight or warmth in the vocals.

@ronrags @dweller Question for you guys. What were your impressions on the bass response of your PrimaLuna when you first got it vs how it changed over time? I feel like it gives more oomph than what I had with the Luxman, though it is looser and not as well defined. I'm hoping it tightens up and becomes more defined as the tubes break in, but I'm also most likely going to upgrade the tubes anyways.

No hum at all on my end with the PrimaLuna, and I am powering high efficient Tekton Lore speakers. The Tekton does have great bass response so it might be that pairing with the PrimaLuna is giving too much bloat on the bottom end. I'm used to having very tight, articulate bass. Again, hoping the tubes break in nicely to do this. 

@dweller you mentioned that you bought yours as a demo unit, so perhaps your tubes and unit were already broken in, giving you the bass performance you're getting.

When I almost have my ear up to my speakers I have literally no hum or noise coming from the PrimaLuna unless I literally cranking the volume to 3 or 4 o’clock (like 90% up), and my source is a Cary Audio tube DAC, which could also be adding the minimal noise that is there. Granted, both sources are plugged into a PS Audio Power Plant P3, so my noise is probably minimal. I’m also using psvane TII 12au7’s instead of the stock driver tubes. I also have some psvane grey bottle EL34s coming my way, but until they get here I am using the stock power tubes.

I do get more noise when playing vinyl but that is due to an MC phono stage with seven tubes, so that's understandable.

@dweller I too have replaced my wall receptacle with a Hubbell cryo'd outlet, and the sound improvement was noticeable. I'd recommend @facten 's suggestion.
