What power cord would you recommend?


I have an Arcam Diva AVR200 and am thinking of upgrading the power cord. First question, is it worth it? Next, what pc would you recommend? I’m willing to spend up to $300 new or used. I’ve read articles on AZ Tsumani II, Van Den Hul Mainstream, Cardas Golden Reference, and Transparent Reference Powerlink etc. etc.
The rest of my setup include:
Totem Model 1 signatures (L, C, R)
Van Den Hul CS-122 Hybrid with jumpers
Totem Mite (Surround L, R)
Van Den Hul Clearwater for a 30' run with jumpers
Totem Thunder Sub
Pioneer Elite DVD Player
MSB Nelson Link III & P1000 Power Base (Cardas Hexlink 5C)
PS Audio high current uo, juice bar, power port, xStream Plus

I mainly listen to Jazz, Opera and Symphony music and watch lots of sci fi movies.

Any other advice on tweaks would be appreciated.

Hands down, in that price range, the Audience
PowerChord. Simple stunning. Really shines in opening up the meds and highs. Very very musical.
Semwin, I really WANT to agree with you but can't on the issues of what to do about pc's/cables. You are absolutely correct about shoddy workmanship as well as seat-of-the-pants engineering by non-engineers (i.e. try it and see if it does anything). It would be nice to believe that the larger dealerships have it all together, but it just ain't so.. They are in business to sell what they can move in quantity and usually haven't heard any of the small brands (like Ridge Street, Empirical, Argent, Pure Note, Elrod etc that have current cachet on the internet). Also, you would think that the larger, better financially endowed cable companies would be better, but it's surprising how much bad workmanship shows up at $4000+ price levels. Talk to the companies involved and they will complain about how hard it is to hire good people... hence the lousy QA.
I have never heard a good answer to the issue of preserving independent entrepeneurship yet protecting the buyer. The only policing action that exists in high end is opinion - both end user and industry insiders. The second is fraught with politics, the first is fraught with ignorance. Internet experience among users may be the only guide, yet we are afraid to name names and the websites would censor any serious attacks on their sponsors anyway.
So I'm open to anyone's new thoughts here.
Why don't you try a DIY pc? Then you can begin to make an informed decisison on buying commercial power cords or more music.
"Musical" Power Cord ?? From my experience a power cord removes unwanted things in the power path, that are getting in the way of the music.

Therefore, the equipment is musical. The power cord just removes whatever was making it less musical. If the audio system is not musical to start with, a power cord is not going to save it.

Thus my earlier comment about the law of diminishing returns. A good $200 to $300 power cord is going to get you most of the way there. After that, you are spending a lot more for not as much return. But if you feel your system is worth it, then go ahead and spend more.
All - thanks for sharing your experiences and expertise with me. I've learned a great deal from all you philes. Now, my quest for the most suitable power cord begins!!! PMP.
