here is my delima............

I have a cj - 2500a, cj - pv 12, alon 4's,rotel 975. i have tube rolled my brains out, settling for amperex nos. I use tara labs vector 2's between the power and pre, ive tried different ic from audio art, to morrow, to audioquest for the other components, one makes the sound to thin, one makes the bass to boomy, I cant seem to get it just right. i use axiom tri wired speaker cable. the problem is i have this mid range, mid bass vacuum that i cant seem to get rid of. i wonder if my system is starting to degrade, after all it is an older system. or is this a product of lets say the speaker or amp/pre manufacture design. i did read some where that the older alons had a problem with the midrange on some of their speakers. just about every thing i could think of to remedy this problem but all i get is back to square one. i did recently have my local power compy come out and was told my box was only 100 amps. i did some calling around on that and was told my house could be under powered, which is just as bad. i have noticed that when i am playing my system and the heater comes on, the sound degrades. and i do notice the fluctuation like others in bad areas in sound from lets say 11:00 to midnight maybe(peak time) this hole in my midrange is not always there, it varies from day to day and time. i do notice that as i turn up the volume i tends to get worse. ive tried replacing all the drivers in my alons, but that lasted for just a while and then the problem came back. also when i turn up the volume, i get very little gain past say 11:00, after that the sound quality gets terrible. any help at all would be very much appreciated..............

It does sound as if you have total system malaise an old problem of over familiarity with what you have. I like the sound of the Nola/Alon speakers. It does sound however as if you need to think about a new pair of speakers. You may want to stay with this company or go in a new direction altogether. The full rich tone of the mid bass and lower midrange is certainly worth persuing.
I would also take the advice to upgrade your house power very seriously. I had a whole new panel put in with more amperage. I had a couple of dedicated lines to my listening areas put in at that time as well. Thats a start anyway.

Perhaps a power regenerator from PS Audio will do the trick.

thank you all for your fine responses, I think I will try to up grade the panel 1st. I do have the down stairs system on a dedicated line though. but let me address some of your responses individually;
Rrog - why do I need therapy?
islandman dan - I think you may be on to something, my room is rather small.
rockadanny - then you know what im talking about, ive heard many complaints in the forums about dirty energy in their areas.
mechan - I was thinking of that, going with a McCormack dna 500, or pass labs 350.5 and maybe a newer preamp like the classic se from cj
wilsynet - if I do anything it will be a whole home power conditioner and surge system, when I put the panel in. and again thank you all for your fine thoughts

rockadanny, what type of system do you have, just curious..........

darn, I had researched your gear and posted a lengthy response with a multi-step plan that did not make it through somehow + I am too lazy to do it again.

In a nutshell...

Good news was you have a problem which is solvable, not a dilemma, which is not. That's a good thing.

Bad news is there is probably several things to do for better results starting with making sure all tubes are strong and operating properly (get them measured if possible) and optimizing speaker placement for best sound.

After that, I do not think you have the best amp to bring out the best in your speakers. That's a topic to keep in mind once you make sure what you have is set up and functioning its best first.

Lastly, but only after the others, a suitable Furman power supply to all devices save power amp would likley help take things to a higher level of detail dynamics and clarity once everything else is squared away prior.
