Finally got my dedicated AC lines installed in my home speakered audio room and am hearing noticeable improvements. Cost for line installation was $120. I purchased the electrical duplexes separately [see 2) below)]. I comment that the rural area in which I live is lightly populated.
Here's some notes:
1) My electrician made runs of 12/3 20-amp wire. One AC line is connected to a single duplex, which powers my digital source; the other line feeds current to two duplexes, which in turn supply power for my two mono amps, the preamp, and the TT. Separate breakers for each dedicated line were installed into the main house box. The AC lines had to be run the length of the house (run the length of the basement then snaked into the first floor), as the main box and my audio room are on opposite ends of my residence.
2) Receptacles that I purchased separately are cryoed Pass and Seymour 20 amp 8300 MRI "hospital grade" receptacles purchased from Chris VenHaus of VH Audio. Electrician let me coat the 20 amp wire ends, prior to insertion into the receptacles, with Walker SST.
3) I had to dismantle and move all of my audio set-up prior to the dedicated line wiring, except for my speakers. For RCAs, ICs, and PCs that I had to disconnect, I cleaned those items and recoated with Walker SST. My mono amps each now sit on 25 lb granite slabs, on the floor, nearby the respective speaker each amp powers. The TT was reinstalled / re-leveled as before, the preamp and its granite slab moved to the bottom of my audio rack, and the CDP left in its original position. I replaced my speaker cables with a shorter length of the same cable (shorter runs due to moving amps closer to speakers). The preamp and TT each were previously was plugged into a Monster Cable HTS2100 Powerline Conditioner; the HTS2100 is no longer used.
Results - it's turning into a very pleasant experience. I hear increased / improved: separation between individual instruments and voices, soundstage depth and width, precision in instrument / voice placement, detail (attack/decay edges, other things in the music I never heard before, etc.), quicker attack and decay, blacker background - in general, better everything. I'm sure the ancillary changes that accompanied the installation of the dedicated AC lines have some impact, but as to what they bring I'm not sure, and I'm sure I don't care. This changeover, for me, is an unqualified success. YMMV.
