What's Going On?? Sound changes every night

O.K., this is what I'm experiencing: Some nights my system is superb and I just get sucked in and have to force myself to stop. This will be for 2-3 night and then all of a sudden, the next night or three, the music looses life and I can't get involved. The sound looses high end sparkle and extension. Things sound closed in a bit and percussions instruments that the night before were right in front of me are now fake with a closed in and shelved down presentation. Cymbals no longer sound like wood sticks on bronze but as if someone threw a blanket btw me and them.

Is this a power conditioning problem? I use a hospital grade outlet but not a dedicated circuit and no power conditioners. Or could it be my DAC which is a Perp Tech w/ Level 2 WrightMods and cryo treament. When the system works right I couldn't be happier but it seems something weird is going on every few days or so. Could it possibly be coming from the local power company and I need some sort of powerful line conditioner?

System:

Merlin TSM-MX speakers
REL Strata III subwoofer
Air Tight ATM300 stereo amp
Joule-Electra LA150 pre-amp
WrightModded Perp Tech DAC
CEC transport or Marantz SE 5 disc changer as transport
Cardas Golden Reference interconnects
TG Audio speaker cables

Perhaps a mood ring will help you determine when it's time to listen. :)

Seriously though, as you suspect, I believe the symptons you describe appear to be the symptoms of dirty or poorly treated AC coming into your home.

You've invested too much into your gear to not take full advantage of what dedicated circuits/lines and proper line conditioning can provide you.

If you did, you're system will consistantly sound far better than it could right now on it's best night.

BTW, the dedicated circuits/lines do nothing to clean the AC coming in from the pole. The dedicated circuits help isolate your system from noise generated inside the home as well as ensuring that your amp has the necessary juice for those loud and/or dynamic passages.

Yes, Tomryan, it has everything to do with the power coming into the house.

That's why some of us have recommended the dedicated circuits/lines and 'proper' line conditioning.
