If it aint broke dont mess with it. However it is a good idea to have a licensed electrician preferably and old guy with decades of experience to check receptacles, and all ground and neutral busses in panels. If theres a transformer have him check that the XO is wired correctly. I was sent to help a guy finish a warehouse job and the companies BEST electrician didnt ground the XO. I am a retired commercial electrician.
Also that audiophile stuff is mostly crap. A friend worked at 3 different audiophile stores here in lost angeles in the late 80's and early 90's. The amps, preamps, speakers, turntable were awesome but the super dupper power cable, $50,000 speaker cables, $20,000 cord plug are all BS.
