In my experience stock power cords arn't enough for power amps. With limited wire gauge to 16 there isn't enough AC power fed onto the amp. In comparison to home brew design that I use, the stock power cord is more quiet(not because the bad mastered shielding but because more power is delivered I guess). The sound becomes more defined and more dynamic. I've used the hospital grade 12AWG OFC AC cable from wireworld.
Stock Power Cords?
Are all stock power cords low quality? And how would you know if its good or bad quality? For example: I have a Classe CA-100 amp, the cord looks pretty beefy.Would a typical replacement power cord in the price range of 100.00-150.00 be an upgrade?and would it make any sonic difference?
