At least some good Hospital grade wouldn’t hurt

Yes, for a duplex under $50.00 I recommend Porter Ports available from Albert Porter here on AudiogoN. For more expensive offerings checkout Furutech and Oyaide outlets at VH Audio.
lowrider57......... I have a dedicated line for my Krell FPB 600 amp and my ARC Ref 6 preamp which i will be adding the Furutech GTX-d r. But not for my Rega Isis cdp. Would you also recommend a dedicated line for the cdp too? I was just going to change the generic receptacle to the Furutech GTX-d r.
For cheapskates, Even ordinary Pass & Seymour 5362 heavy duty outlets are superior to most hardware store ones $5 or so.. Here is a Amazon link https://www.amazon.com/Pass-Seymour-Specification-Heavy-Duty-Receptacle/dp/B008SBH18M/ref=sr_1_15?ie... They continue to hold their grip for many many years. I use them with my $$$$$$ stereo.
Avoid Leviton.. they are really junk and the outlets lose any grip quickly.Audiogon, if the link is forbidden sorry I did not mean to break any rules.
Googling 20 amp duplex on 15 amp wires NEC says no. The NEC is not the wire police. They are guides used by electricians as to what they can and cannot do since they are contractors and THEY have legal and liability concerns. For the apartment dweller, or homeowner. Those concerns are not a law, You cannot go to jail for using a 20 amp duplex on a 15 amp line! But in the event of a fire caused by your 20amp duplex.. Your insurance company may have problems... The fact is the breaker is going to trip (15amp) before your 20 amp duplex gets to flow 20 amps, over heating the 15 amp wiring in the wall and box.
So the answer is technically no, you cannot use that 20 amp duplex on a 15 amp branch, and no electrician will install it (maybe)... But YOU CAN, if you want to break the rules, knowing the consequences. Anyway, If you cannot sleep at night knowing you have done this, then do not do it. I have no problem with using a 20 amp duplex on a 15 amp line. (BTW I use a 20 amp circuit for my system)
According to various Googled sources, it IS allowed to use 15 amp receptacles on a multi receptacle 20 amp line. There are conflicting statements in the NEC code. But the consensus is the multi 15 duplex on 20amp branch is OK per NEC. On a one only single duplex for a 20 amp branch, no. that outlet should be a 20.As for using a 20amp for a CDP. Who cares? A CDP is using 20 to 40 watts, maximum. The power cord for the CDP can be 20 gauge magnet wire, like Mapleshade.. Or a 7 gauge Pangea.
You can have a 20 amp circuit with one 5 watt light bulb. The bulb uses 5 watts, whether the cord it uses is capable of delivering 20 amps or is only some 22 gauge magnet wire. The light bulb does not care.I would add, if you are so uncertain, do NOT do it. Find someone who can deal with it. Making mistakes when it can be dangerous? Just do not do it. Or at least find out enough to feel confident.Fiddling with stuff you do not understand is not a good idea.
czarivey....No u are wrong. My cdp is not on a dedicated line. So i will be adding a dedicated line for that. But i already bought a Furutech GTX-d r 20 amp. At first i thought i could use it for my non dedicated 15a line with my Furutech GTX-d r . But not according to Elizabeth if i am reading her answer right. But since i want to have a dedicated line for my cdp i might as well go with a 20a dedicated line so i can use my 20 a Furutech with my cdp. Does this make sense?

It would make sense to add a second 20 amp dedicated line. You can use your CDP, and in the future add another digital device such as a dac or streamer. It’s best to isolate analogue from digital.
Or you can keep the 15A line as long as it is properly grounded at the receptacle and at the circuit panel.
czarivey, Did you buy a used home? Or move into a preexisting apartment? I guarantee the duplex outlets there are all old as the building is. No normal person replaces any duplex until they are broken. that usually means the duplex outlets when YOU move in, are already 10 to 40 years old. When I move into a new apartment, I replace all the outlets with new ones right off. Ditto the light switches.(since I stay more than ten years.. it just makes sense to me.)So generally replacing outlets is more like replacing nearly broken down crap that works, but does so poorly, with something that will work well for years to come.++++++++++++++++++++++++++++++++++++++++++++++++++++TTman.. As for the quad 20 amp circuit. That is all you need, usually. Unless you like to play music at over 100dB (which is really loud)In that case it will not matter anyway, since you will soon be deaf. and the distortion in your ears will mask any in the equipment.
So I am saying you do not need a separate circuit for your CDP, or preamp, or any other equipment. If you want some improvement, I would suggest getting a small powerline conditioner for your CDP, plugged into the same circuit as the amp.
... 20 amp duplex on 15 amp wires NEC says no. The NEC is not the wire police. They are guides used by electricians as to what they can and cannot do since they are contractors and THEY have legal and liability concerns ... Those concerns are not a law, You cannot go to jail for using a 20 amp duplex on a 15 amp line!o, you will not go to jail. But in the US, almost all jurisdictions rely primarily on the NEC, so it will be a violation of local code to put a 20A receptacle on a 15A line. That's because the breaker would not reliably trip if the load exceeded 15A. The breaker's primary purpose is to prevent the wire in the wall from overheating.
You can use a 20a receptacle on a 15a line.Correct. But it's a violation of the NEC and potentially hazardous, because the 15A breaker can 't protect against the potential 20A load, would could cause overheating of the wire inside the wall.
"Over heating of the wire in the wall. But the wire is 12 gauge anyway..... ??
ALL the wire in most places I have lived is always 12 gauge in the wall anyway. 15 or 20 amp circuit.
The requirement for a 20 amp service line is 12 gauge wire....As long as we are getting all technical.
So if you line has a 12 gauge wire in the wall, even though it has a 15 amp breaker, then the fear of overheated wire is lost on the 12 gauge in wall wires. (naturally this precludes really long runs.. But whose house has rooms 200 ft long anyway???)
elizabeth. Yes that is what i would do if i could , I would use my dedicated 20 amp quad circuit also for my cdp. But unfortunately that quad dedicated 20a circuit is right in back of my amp and preamp. My cdp is a distance from that quad circuit. So thats why i have to put in another dedicated line for the cdp. So i will then just put in a 20a dedicated line with the Furutech GTX-d-r .
The requirement for a 20 amp service line is 12 gauge wire....As long as we are getting all technicalNot necessarily. Check the NEC and your local code. Code also almost always (there are some exceptions) requires that any "device" (receptacle) connected to the circuit have the same rating or better as the breaker.
@tattoo, just so I understand, the 20A dedicated line is installed with 2 duplex receptacles. 20 amps would require commercial receptacles. Is this correct?
Does a receptacle and 15 amp line already exist for your CDP?
In any event, you will be adding the Furutech and I assume running new 12 gauge Romex to a 20A breaker at the circuit panel.
Make sure your electrician installs the ground wires from both dedicated lines to the Ground Bar in the circuit panel.
lowrider57......The 20A dedicated line right now that my electrician installed with 2 duplex receptacles says TR . They are white. I dont know what you mean by commercial. From what i found on line TR stands for taper resistant and sell for $3.50 ea.Very cheap and prob garbage for audio. Right now im using that for my amp and preamp until my 2 Furutech GTX -d r come in the mail and will replace the TRs. Also right now my CDP is on a non dedicated 15A. And waiting for the 20A Furutech GTX-d r to come also in the mail , then i will have my electrician run the dedicated 20A line and put in the Furutech for my CDP and have him replace the 2 cheap duplex TRs and install the 2 Furutechs for the amp and preamp.
Running both lines to the ground bar in the panel means that they will share the same ground, less chance of a ground-loop.This is required by NEC in the US. All grounds must be connected to the ground bus at the service panel.
If you have 12ga wire and a 20A breaker, just change the receptacleCheck NEC and local codes. How long is the branch circuit? Is the wire in conduit or confined space? 12ga might not be sufficient and even when it is, it's a minimum spec. You can reduce voltage drop, for example, by using 10ga wire.
