Update power cord

I would certainly give the Cerious Technology CT GE pcs or the Core Power Technology pcs a try. both are superb and 'reasonable' .

This is what I would do first before adding a Chassis IEC socket to your amp (unless you're able to do yourself). Go buy a Furutech FI-15ME AC plug. Install on your fixed cord and I think you will find the results very satisfactory. I've done this to int. amps/CDP's and was amazed how much better things sounded. Very good product along w/the FI-15E IEC connector. Made a wonderful improvement on my Arcam 10 int. amp

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.
