Brightness Differences Between Daytime and Evening

Dan: What you describe "dull" is still the AC power. It is the problem I had on my old house. It is where I first got introduced to power conditioning a few years ago.

So how did you fix it, Sugarbrie?

You may want to start with speaker placement and room accoustics. What is your room like? Thick carpeting, heavy curtains and soft furniture will suck up the sound.

My problem way back when was bloated bass making everything dull. Cleaning up the power and adding better power cords solved it for me.

I think the likely answers are as you suggest, but there can be another variable, depending on whether your observations are for continuous listening during daylight going into night--your equipment reaching its optimum operating temperature. I find my Jadis amps sound considerably better the longer they've been on, although after about 6 hours they level off. There may also be less ambient noise around you as well in the evening, depending on where you live, which makes it easier for you to hear all the details and makes you more relaxed as your mind doesn't have to work as hard to listen. I'm sure Detlof has some psychoacoustical explanation for all of this!

Rcprince, I wished I had, but I'm afraid I haven't in the least, except for the fact, that I share your experience. As far as the equipment goes, yes, there is less hash in the powerline and my Jadis gear will indeed behave in the way described above and yes, after a day's chores, we can let our hair down , often enough as I do, ( for ahem, srictly medical reasons of course ) with a good glass of red, so we are less jittery, I suppose, less critical, though I must say, I can rejoice in my system also during the day or hate it in the evening, when the occasion arises. I tend to think, the difference we all experience is probably more system dependent, though I won't discount a psychological element in this, which I would guess has to do with the fact, that generally at nightfall we tend to be closer to our psyche, closer to our actual being, for better or for worse, more right brained, if you like, than left. But what do I know. Most psychoacoustical explanations of what we experience when enjoying music, fall terribly short in my opinion, but on the other hand, I don't know any better either. Wished ASA would read this. With his nimble brain and original thinking, I'm sure, he could say a word or two about this. Cheers,
