My system acts weird

My system is Audio Aero Capitole, Yba Passion integrated and Harbeth sHl5 speakers, kubala fascination interconnects and kubala expression speaker cables.
I have noticed that most of the time it sounds just ok.(not like it should) sometimes it sounds just plain horrible and sometimes it sounds just right. The sound can improve dramatically for a period of a few minutes and then collapse again. The best performance was during the long weekend - the music was just flowing, lovely and involving. I assume that it could be the power(I live in an old condo building). To rule out the cdp and amp problem I used borrowed CDP and AMP for a while and all the time problem still existed.
So I bought a line conditioner "Sound Application". Even though it does make a difference it did not resolve the problem.
The symptoms of a "bad sound day" are:
base is all over the place-boomy and overwhelming
Soundstage is flat and not well defined.
Entire presentation is just not enjoyable.
I consider buying a re-generator and so far it's ether PS audio Premier or APS PurePower.
If any of you had a similar problem please do share your solution.

Avialuf,
Does your system sound better late in the evening or in the early morning hours when most others in your area or building are asleep?
What other appliances are on the same circuit as your audio gear?

I think the problem might be due to the power (AC) being supplied to your "old condo building" and all the other items from neighbors that are running and polluting the AC. I've never had this happen to me personally because I live in a newer development in my home. I have read of similar situations over the years that sounds like what you are describing. I'm uncertain as to what the solution is. A different way to clean the AC would be with a used isolation transformer (see my power filtration picture in my system). I have a friend that solved his AC problem in his apartment by plugging in an isolation transformer to the AC wall outlet (he wired it for that) and he installed a high quality AC outlet on the other end of the isolation transformer that he plugged his system into. I don't know if that would help any better than what you are currently using.
