I'll put in a good word for the Hero, which I use. Don't know anything about the others, though. My personal theory is don't spend too much money on wire - you will not hear enough difference between a company's highest and lowest price products to justify the often ridiculous price differences. Wire is not going to make your system sound better - everything in the signal path does degrade the signal, so it is a question of not doing harm. Just go with a good company's product in the lower end of their range. I actually was going to go with an even cheaper interconnect than the Hero, but I got a really good deal on them.
