I'm so interested in the idea that the power grid is cleaner during the wee hours. There may be something to other night time listening factors mentioned in this and other similar threads: mellow time of day, no noise outside, etc. But there are times my system sounds WAY better than usual, and they're always in the middle of the night. The music is more involving, with better depth, detail and balance. Soundstage is deeper, wider and just more coherent overall. It sucks me in and reminds me why I'm so passionate about this hobby.
I've spent years of my life in recording studios, so I'm confident that I can rule out other factors. I know what music sounds like when I'm fatigued, or when my ears are fatigued, etc. For me, this isn't about being focused, relaxed or whatever. There is something wonderful happening with my system during the hours that most people sleep, but it's elusive. I've begun measuring the voltage coming out of my outlets to see whether there's a correlation there. During the magical times, it seems to hover just above 117 volts, and goes a volt or two higher during the day. But I don't think that's it. I happen to have a couple of outlets in my studio hardwired to a variac, decided this morning to experiment with dropping voltage to 117 when it's running higher, but at the moment it's already at 117. It'll be interesting to see, but intuitively I don't think it's a simple matter of voltage (even though running lower voltage via variac can be the key to making a guitar amp sound magical). I really do think it's the cleaner power.
If anyone else with experience can chime in on this, I'd love to dig deeper on this single point. The level of sonic improvement I'm talking about is greater than that afforded by new old stock tubes, or even by some component changes I've made. It's greater than the difference made by changing out interconnects (and I say that as a guy who does hear the differences). If I can isolate the principle at work, I'm hoping I can harness it. For example, I'd much rather spend money on a serious power conditioner as opposed to upgrading my turntable, if it'll give me the 3:30 a.m. magic whenever I want it.
Can anybody help shed additional light here? Who has experience with this? Is the Richard Gray stuff worth looking at? Is there a cheaper solution? My funds are limited, but I've pretty much got myself convinced that whenever I next get a little bag of money to spend on audio it'll probably need to go to cleaning up power. Somebody out there must have already chased this dragon, how did you do it?
thanks in advance and sorry for the semi-rant.
