In Reply to: RE: this is the issue posted by Cpk on December 08, 2016 at 10:03:53
The guy has a separate room on the back side of his audio equipment that cannot be seen from his listening room. (I would guess the room is about 3.5ft to maybe 4.5ft deep running the entire width of the main listening room.) The electrical panel board as well as the branch circuit conduits are surface mounted. He might be able to use PVC conduit and PVC/plastic outlet boxes, if local electrical code allows it to be exposed. I think MC cable would be a better way to go. he could use malleable aluminum boxes for the receptacle outlets. What do you think? Any other Ideas?

My preference would be 10awg and plastic.
Here is what the guy has now.All the dedicated branch circuits are installed in their own EMT steel conduit.
The guy says the branch circuit wiring installed in each conduit is braided together. The hot conductor, the neutral conductor, and the green insulated equipment grounding conductor. One dedicated circuit is 240V 30 amp for a Boulder 3060 power amp.
My question is could this braided wire installed in a steel conduit be causing his SQ problem. Especially for the power amp. To me even though the wiring is a branch circuit fed from the electrical panel it looks to me to be basically a shield braided cable. The 3 conductors are #12. I also think they are stranded wire. He didn't say if it is a factory braided assembly. I think it is....
.
Here is his first post:
I had a custom room built and spared no expense. Hired a power consultant who designed a system with a 15KVa isolation transformer and a custom breaker panel that feeds only the audio room. System incorporates isolated grounds and IG outlets. The advantage I have is that I know how my system should sound because I only changed one piece of equipment from my old to new room. System is Wilson Alexandria, Boulder 2110 pre, 3060 amp (had 2060 before and they sound very similar) and full vivaldi stack. System had incredible detail and thunderous bass. Now has decent detail and soggy bass (hyperbole). After a year, I had the electrician take the isolation transformer out of the system and run a new line from the street to the breaker panel. Everything is much better now, but still has a layer of syrup over the presentation that shouldn't be there and loose bass. Room acoustics are a bit different, but the power is the biggest difference. What gives?
His second post. His response to mine:
In metal conduits. Single run of 12G braided wire in each conduit. Run from subpanel is <8 ft in all cases. Probably 20 or so lines coming of the subpanel. Don't know about the interconnects. There are 2 legs, but all my equipment fits on one leg. Old room had lines slowly added over time. Amp was running 240 in there as well. I believe it was wired with 10G solid core cable. There was a mix of metal and "plastic" conduits and boxes in the old room. ( BTW, had serious ground loops in the old room, but the Boulder gear was fairly impervious to it. I demoed a single ended Lamm amp and it buzzed like a fiend!) Using a mix of hubbell and voodoo (cryoed hubbell outlets) in new room. Plastic plates.
So what do you think? Any ideas?

The conduit in not good. 12awg stranded in wall is going to sound different then solid core. Since probably 100% of power cords designed with solid core in the wall, I'd go back to that. Not a big fan of Hubbell's. Braid isn't great but less impactful then above
