good power cord under $200

Not much difference between them.

The most important criteria is where they will be used and the gauge of the cord.

Use a 9 awg cord for power amps and conditioners, and use a lower gauge (12 - 10 awg) for sources and preamps.

2nd MAC Soundpipe (My Audio Cable). Very affordable. Nicely made. Actually better quality and less $ than a DIY put together using instructions and parts from "Parts Express".

Morrow Audio PCs are terrific value. He advertises here

I have the vd power 3 and like it a lot.I have not compared it to the others,but I have copared it to zu cable birth and it is much better.

Take a look a Zu pc's they do auctions on epay and you can get a new one at a good price.

I bought their BOK and it is not quite as good my Shunyata Diamondback but way better than some others that I have tried (none of which are on your list.)

If you are willing to go used I would recommend the Audience or Shunyata you cannot go wrong with either.

All my equipment is SS so I do not know how they might work with tubes.
