Replacing generic RECEPTACLES

Scratching my head, Why does anyone think that they need a 20A dedicated circuit for a CDP? I see the purpose for using a better outlet receptacle, as a better tighter connection and grip, is always a plus, but I see no purpose in having a dedicated 20A circuit for a CD player and no players that I know of that comes with, or requires a 20A cord. It would surprise me if any CDP or combination DAC and transport pulled more than 5 amps and there are very few power amps that actually require a 20A circuit and have or require a 20A cord. In fact lower amp equipment should not be used in high amp circuits. If something fails, something might burn before the breaker trips.
I have built and wired a number of houses and garages all to UBC and NEC code and can tell you - both 15A and 20A residential circuits are commonly wired with the same 12/2 w/ground Romex wire.....just sayn...Jim

My point is: If you already have a 15A service with receptacles where you need them and there is not already  a host of other devices plugged into that circuit - that circuit would be most adequate for your cdp and possible other devices. I can understand upgrading the receptacles and to a point, power cords, but installing a new 20A circuit for a CDP or even a CDP and one or two other components, is nonsensical....my professional opinion...Jim

I should make clear on my previous statement - that is if your home is relatively modern with a good electrical system, or is an older home with a professionally upgraded electrical system. I can see the value in having a dedicated 20A circuit for your high draw power amps and large powered subs, however....Jim

@tattooedtrackman As long as there is already a circuit available where you need it and that circuit doesn't have other  devices or appliances plugged into it, why create another circuit. Every circuit in your house is tied into the same ground and same neutral bars, adding another circuit isn't going to change that (for that you would have to add a complete new service and that would be a bit expensive) and you do not need a 20A circuit to run a CDP. Yes you can install a 20A receptacle where you need it, for the sake of getting a much better receptacle (no one will throw you in jail) and your CDP and other components will plug into it....Jim

@geoffkait  My impression is most naysayers couldn’t care less about the item under debate.
Not necessarily. The OP asked for help and advice; if some of the advice is false and it might cost them, unnecessarily, a good amount of extra money, the OP should be told.
The idea that you need to install a dedicated 20A circuit to get better sound from your CDP is bogus. The idea that - if you put the ground leg on the top end of your breaker panel's ground buss, as apposed to the bottom end of the ground buss, will eliminate noise coming through the ground loop - is bogus The grounds are all commonly connected to the same ground loop....just sayn...Jim

@tattooedtrackman  I don't believe that a CDP necessarily needs to be on a completely dedicated circuit, but would avoid sharing a circuit with appliances or even a high currant power amp.
Because good conductivity and tight connections is important - I do believe in the use of quality receptacles and because there is a bit of noise and grunge introduced from appliances and even down line transformers, and minor voltage dips and spikes in nearly all residential electrical circuits - I do believe in the use of good power conditioners for both video and audio gear...Jim
