Power & line conditioners - One size fits all?


New house. 4 dedicated lines. Apparent ground loop issue. Looking for the least expensive way to fix it all. (ain't we all?)

My thinking is to install a 5 - 7 KVA, isolation transformer at the breaker box, and redirect the ded ckts from a sub panel, if I can shoehorn it into the wall, that is. (it's like 90 lbs.)

OF all the listed issues, the most irritation comes from a harshness in the mids. sometimes Vocals have an edge I just can't stand, mostly female. Music, no problem. Female singers, poor recordings, problem. All my gear is less than two years old. Anthem, Krell, B&W, Velodyne, etc.
I'm thinking all I'll need then is line conditioning for the front end. Right? That being said, which way do I go from here to achieve above average performance? Which "one" LC will do it all? Or is there just one?

No experience in the line conditioning deal. Not a lot of faith in it either, but after seeing all the rhetoric from people online & reviews, if indeed a gain in sonic quality is to be achieved, I'm all for it . . . eventually.

I'm looking for a slam dunk here. . . hopefully.

The harshness you are talking about is called sibilance, the "ssssssss" sound on female vocals and poor recordings. What source are you using? Did this problem start after you moved to your new house or has it been there all along? Which B&W speakers?
Trying to cure sibilance is not always an easy thing to do. As Fatparrot stated, adding a LC is always a good idea, but I agree with him that it's got more to do with the gear choice. I'd start with the source. Try a tubed output CD player, something like a Jolida or Ah! Njoe Tjoeb, which can be had used for not a lot of money.
