Rick next time you see used Harmonic Tech Pro-AC11 power cord here for $125, buy one and use on CD player first, because it is the most sensitive to change of cord it will show biggest improvement, of course it must have removeable cord. Pre-amp and amps also will also improve in that order. If you don't like you can resell here for same price as you paid....."try it you'll like it" regards Sam
Power Cord Advice
I have the following amps in my system, Acurus A250, A200, and A150. Would I realize a noticeable improvement in sound and dynamics with higher quality power cords. Also do other components in my system need upgraded power cords or just the amps. Thank you so much for your help. Rick
