after market power cords for power conditioner or amps etc


Hello,  my front amps, subwoofer and A/V processor are plugged into a Furman IT 20I.  I was thinking about getting some middle of the road after market power cables to experiment if the power cords really make a difference.  I am thinking it would be a good idea to begin by replacing the power cord on the Furman IT 20I instead of incrementally repacking the A/V processor and amps chords.  Please advise.
Thank you.

Good ones definitely make a very easily noticeable and cost effective improvement. No doubt about it. 

The difference using it on the Furman will not be greater than on anything else. Go ahead. Get one. Move it around. You should do that anyway. Then you will see.

However, you can get better results from a $160 Synergistic Research Orange Fuse than from most $500 power cords. There's even a 30 day guarantee on the fuses. Which you won't need, because they're too good to return. The total improvement from 3 of these for less than $500 vs one $500 power cord will clearly favor the fuses. Even if you get a real good one like Synergistic Research Master Coupler used the fuses will still be a better deal.
