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
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
Start with CD player, then Pre-amp, then Amp. Power cord upgrades are the MOST significant improvement. My Electraglides,ie Reference and Fat Boy were the most dramatic upgrades than my $4000 CD Player!! Power cords DO make a difference.Buy them USED and save alot of money.Research them first. All cords do different things in systems. Check out the BMI or Delta Lab power cords on the Auction here at Audiogon. Great cords at Minmal prices that compete with much more expensive manufacturers. GOOD LUCK. Oh, don't forget upgrading interconnects and wires.
