Update power cord


I have a Rotel RB 991 power amp driving a pair of Vandersteen 2 ce speakers. t has a captured power cord now would spending a few bucks to have an IEC power outlet installed and upgrading to a reasonable cost power cord make a difference. I would like to smooth out the top end a bit.

I am a believer of upgraded power cords after listening with my own ears but in your case the cost may not be worth it. I would spend the money on a better amp. I think you will notice more of an improvement with a better amp and then trying a better power cord in the future.
I'm also believer, but would not spend for aftermarket power cord. For me the magnitude of improvement isn't enough justified for money spent. $0 stock power cord will still have much better ROI.

an easy tweak-replace the wall duplex with a generic hospital grade unit and hear the difference- YMMV
