I see that Outlaw price on XLR cables in quite high ($105 per pair), I was looking for other sources. I see that PartsExpress sells XLR microphone cables at about 8$ per cable. My guess is that microphone or not, it's still the same cable (22 pure copper, etc.)

So what do you think of them?

That price is for a pair of 3.5meter cables (10-foot), whereas the cables from Parts Express are 3 feet. Since Outlaw appears to be out of the shorter lengths, you might consider Blue Jeans Cables - it's a few bucks more than the microphone cables, but I trust Blue Jeans to make a good cable for home theater use, whereas I don't know as much about Dayton's mic cables.

I recently purchased a set of balanced XLR cables from these people:

They came highly recommended, the price was right and I liked the fact that they're using gold connectors.
