Well, I've been using Roon regularly--as in every day--for more than a year now. But just today I discovered something which improved the sound of Roon again in my system. Now, this may be totally system specific, but since this sort of thing seems to apply to most CD players and computers I've owned, I suspect it may well apply more generally.
The tip? Computers, routers, CD players, and--yes--it seems the Roon Nucleus+ can benefit from an occasional hard reboot. Sometimes such hard boots fix obvious functional glitches. But they also seen to clear out sonic cobwebs.
Lately I'd been noticing a greater sonic gap between the sound of programs played through Roon and the same program played directly through the Lumin App software, be it internet radio, Tidal, Qobuz, CD quality, MQA, Hi-Res, or my WAV music files. Roon was sounding less three dimensional, brighter, and less full in the bass. Oh, it "worked" fine as it most always does--no software glitches. But it just seemed like either I was just more tuned in to annoying sonic aspects of Roon's presentation as time went on, the Lumin App was getting better sonically, or something else was going on.
So a couple of days ago I turned off the Nucleus+ AND its associated Keces P8 power supply to seem if relieving the system of the electrical/RFI/EMI caused by the Roon Nucleus+ would further enhance the Lumin X1 playback via the Lumin App. And that did seem to have a bit of a positive effect.
But then I remembered that when I've turned off the Nucleus+ in the past I had not also turned off its Keces P8 power supply. Thus, at some level, the Nucleus+ never underwent a "hard boot." This time it certainly did.
Lo and behold, turning the Nucleus+ and the P8 back on again and listening to Roon again was a truly shocking experience. From the first moment, even with those electronics cold, gone was the bass thinness, the brightness, the lack of three dimensionality. Roon now sounds truly wonderful--again or maybe better than ever before. I'll have to do more comparative listening between Roon and the Lumin App again, but Roon certainly has never seemed quite this sonically captivating before.
