Power Cables


I am currently upgrading my system.  I had a pair of XLO Ultra speaker cables sitting around and was very impressed with the improvement over the original Monster cable.  Having come back from Axpona, I am wondering what fellow Audiogon members would recommend for a power cable with tight bass, superb mids and extended highs that would help to produce a very full, wide and deep soundstage.  I am looking to replace the cable on my Adcom GFA-5802.  I do agree with philosophy of starting with the power.  I have demoed one other power cable and the difference is immense.  Thanks in advance for the advice.

You could try Synergistic Research's new RED or BLACK PC. I haven't heard them yet, but they have similar attributes as their highly regarded fuses. Very affordable with a 30 day trial offer.
@spipa, I just received the Synergistic Research Black PC from the Cable Company and it is amazing. If you are looking for an upgrade for your Adcom, this may be it.
Deep, tight bass, excellent imaging and a soundstage that extends beyond the speakers.

Spipa, I just spent several weeks reviewing several brands of chord for my C50 / 601 McIntosh set up.  Had two separate Mc dealers suggest Audience chords and that's what I decided to go with.  More detail, tighter control and very musical.  Best my system has sounded. Worth the $.
As a owner of mc452, I dont think a powercord will do so much to an amp.  I have no idea why people could hear so many different things from copper /silver what the cable is made of.   I can sell you my nrg2 if its not too cheap to you. I bought it because it looks better than the standard cord. 
For amps, I have used all iterations and generations of PS Audio cables. Currently running AC-12 and love it. (I'm using all Shunyata for my front end). 

I don't know much about electrical engineering, but keeping it simple with high quality copper of a decent gage has served me well on amps.
