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
