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.

I would check High Fidelity MC O.5 (not a power cable) I would plug it into the same wall socket that has your existing power cord plugged into. Well below your budget, with all of the quality you are looking for in sound. and comes with a return policy if its not what you want. BUT I MUST WARN YOU they are very addicting the more you add to your system the better the sound gets. I started with 1 and now up to 8 with the notion that i will be adding more.

I would suggest you to grab MC452 or go with used 501s or 601s before you spend any money on power cords. 
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 $.
