How important is it to replace your generic receptacles with audio grade receptacles . I already replaced my stock power cords to high end Shunyatas. Would it still be necessary to still change my generic receptacles to audio grade?
They just fill the wall with magic pixie dust whilst making snide comments in public to each other about the new family that moved in down the street, and the vibrations of the wires mysteriously disappear.
A lot of this information that is given on this thread is wrong and tread lightly when listening to some of this. Most new construction will use 14g wire for 15 amp lines and most use 12g wire for 20 amp, never smaller but you can use 10g. Never assume anything. No builder is going to pay a premium of using 12g wire for 15amp circuits. I have purchased and built 5 new homes in the last 18 years and every builder in every state has done this. We are building a new custom house now and this builder does the same as the other 5. If unsure, open your panel and verify the wire used. Another thing you should do is have either an electrician or your local utility come out and place a device over your circuit to show exactly how many amps you are drawing on the line. There are guidelines on how many max amps you want to draw. For example, on a 15 amp line, you don’t want to go over 10 amps, this is just an example, not sure 10 is accurate, it might be less or more, but never close to 15. in my latest custom house in my dedicated audio room, I have 6 dedicated 20amp circuits. Cheap to do when building. Large monoblocks, used to use 2 large powered subwoofers, 2 large motor hanss t-60 tt, pre, dac, and other equipment, and the circuits can go fast. Without the subs, I use 4 circuits. Overkill, maybe
inna How do you people deal with vibrating wires in the wall ? You think it’s nothing ? There is an external vibration and vibration created by the current.
>>>>>That’s quite so. That is why there are such things as duplex outlet covers that act as resonators and large (constrained layer) Marigo Dots for walls and even crystals for walls. Herbies Tube Dampers on power cord plug, anyone? Not only is seismic vibration an issue but when music is playing the walls react accordingly and vibrate like drum heads. The only good vibration is a dead vibration. ☠️
Loserbreath must live in a dilapidated rooming house to be so concerned about the structure not being able to dampen reflected sound waves. And being so knowledgeable about the NEC, has ironically created a fire hazard by stuffing flammable foreign materials into receptacle device boxes. But then, box fill is only a concern for “old men that write books of doctrine”, and not a worry for some ignorant people. That sounds like a big liability when it catches fire and burns down the rooming house or group home or whatever it is. Beware of these risks folks, and keep your homes safe by not embarking on fool’s errands.

Very noble stance sw, it might have been your original intent, however as this thread progresses, recent posts have you straying from your said stance.
Since the subject of vibration through receptacle covers was mentioned, I'd like some advice. The covers on my duplexes are not perfectly flush to the drywall so I'd like to secure them. I have two 20A dedicated lines coming from a subpanel, then wired to Hubbell duplexes. I'm using large non-magnetic stainless steel covers which are very rugged.
I want to insulate the inside of the covers to insure a more secure fit. Should I use rubber or Sorbethane, or would there be any benefit in using carbon fiber fabric or tape? All this talk about buying Oyaide carbon fiber covers has me wondering.
Hi @elizabeth. I saw your earlier post about Blu-Tack, I didn't realise that you spread the product over the entire duplex cover. What's your take on RFI leakage thru the AC receptacle; does this need to be treated? Or is vibration control the only aspect that needs to be addressed? A lot of folks are spending big money on carbon fiber receptacle covers. Thanks.
I get that the Blu Tack is only on the backside, that's where I want to use damping material. So, I intend to stop vibration at the receptacles, but do you believe that this area also needs treatment for RFI?
I'm not going buy carbon fiber treated covers, but I'm still looking for an explanation of how RF can be generated or exist at the AC receptacle.
Thanks so much, Elizabeth, terrific explanation. Now it makes sense why you have the quartz crystals in different areas, and why so many tweaks are for sale to treat these same areas. I was aware of possible RFI being found in the obvious areas such as unshielded AC cable and transformers. The Crystals and similar tweaks to be used system-wide seemed unnecessary to me. The Greenlee tool could be useful. Thanks again.
It’s a common misconception that crystals generally operate by absorbing RFI/EMI. In fact, crystals operate in most audio applications by absorbing vibration. For example, in room corners, in proximity to ekectron tubes, on output transformers, on top of tube traps, and on cable connectors, wall outlets and windows. The only good vibration is a bad vibration. Having said all that I wouldn’t be very surprised if someone somewhere could find a place where crystals improved the sound by absorbing RFI/EMI.

>>>Since I am the creator of the first comprehensive crystal based solution for audio applications - Brilliant Pebbles - bear 🐻 with me, gentle readers while I address is comment briefly. Over a period of time starting about 15 years ago I discovered a great many location where crystals (my products are not individual crystals but groups of crystals of various types and sizes) improve the sound. I also discovered locations where their use is either ineffective or hurts the sound. Furthermore, as I just mentioned most locations where crystals improve the sound they operate as mechanical and acoustic resonators. If the entire 3D Space of the room is mapped out for sound pressure level, those locations such as room corners where sound pressure levels can be 4-8 dB or more higher than the average SPL in the room. And beacause crystals are resonators caution should be used when applying them to electronics and isolation stands, for example.
Crystals act as vibration absorbers due to the spring like behavior of atoms in the symmetrical atomic structure of the crystals and the reason multiple crystals are more effective than any single crystal is because the operational bandwidth is wider. Power to the pebble!
I’m gonna throw my recent experience into the mix. my system VPI prime, Hana SL, Lehmann Black Cube SE2 Bluesound node 2, Schiit Bifrost multibit. Primaluna Dialogue Premium int. Focal 1008be2 Audio sensibility wiring.
As I moved from Yaqin 100b to the primaluna , no contest. adding the Focal speakers took me closer to a wonderful sound that I was quite happy with in my 11X16X10 room.
I had bought some Hubell 5362 outlets a while ago and never installed them.
I had had an electrician run a 20 amp line to my stereo before I made my equipment upgrades, however they installed their outlets, and didn’t really attach the box to the studs.
Well I finally had some time to replace the outlets and attach the box to the studs.
To say that there was an improvement would be disingenuous.
I had more bass, more micro detail, deeper soundstage, and wider.
Now I need to get some bass traps.
But I am a believer.
The crappy outlets they installed were less that half the weight of the hubbells.
