Power cable question.

Like most things in audio, the biggest bang for the buck begins by moving above minimum quality. In this case the stock cord is the minimum quality.

Almost any of the power cords discussed and sold at Audiogon will help your sound. As for money, you can spend as little or as much as you can stand.

The Jolida is a fine unit, but since it retails for about $1100.00, that extra $400.00 is a fairly high investment. I would start with used, maybe a Purist or Cardas.

I just took a look at classified here at Audiogon and saw a Cardas Hexlink power cord for $75.00. If this or another similarly priced (used) cord does not suit you, your likely to be able to resell for very little or no loss.

Some good inexpensive, but much higher performing alternatives would be (in no special order) Virtual Dynamics (cryo'd versions), Tek-Line Audio, Absolute, Mr. Cable (made by Tek-line, sold direct), and the Audio Magic X-Stream. All of these cables are under $100 (some are $50 to $70), but will clearly outperform stock cords by a large margin.

The best power cords I have ever used were the ones I made using recipes I found on Audioasylum. The cost is relatively low, about $50. The sonic improvement is huge. I had other cords which have all been replaced because the home made were so much better. The removal of grain and bass improvement is obvious. The only real investment on your part is the time.
Purist makes great cable and so does cardas. I have both in my system now.
The PS Audio stuff makes a noticable improvement. I like all their power stuff. If you can, get some power ports and run a dedicated line or two for you system. I thought it was snake oil, but the power stuff really works!!!

The Asylum cords have worked well in my dedicated headphone system (see www.diycable.com for kits and assembled versions). Either these or used cords here on Audiogon should have a positive effect (tighter bass and cleaner highs). I use Silver Audio Power Burst cords in my main system only because they were the first I tried and I was happy with them. I have also been happy with the Ultimate Outlet (blacker background around music). Having a dedicated UO for digital equipment and another UO for the rest is yet another jump in clarity that PS Audio recommends and that for me was worth the cost.

Nobody has mentioned JPS Labs Power AC. I like it a lot and there are some favourable reviews at Soundstage also.
I found that the Harmonic Tech AC-11 sounded completely different in my system than the JPS Labs. All the power cables do have a different character. I tried the 15amp (stock) cord that came with the PS Audio P300 on my amp, and it improved the bass tremendously but, it was sour in the treble. So I don't think it's true that just any cheap cord will automagically give you a perfectly satisfying sound, unfortunately you still have to find the right one just like with other wires.
