This is a tad late, but I use Mogami XLR cables with. I haven't A/Bd with other cables (given they're so affordable), but they've gotten good reviews here and on Agon. Can get them at any pro audio site (I bought from Markertek for $60 for a pair (6 ft) including shipping).
I went this route via proaudiola and it took about a week, but I've been very happy with the end result so far.
Gear Slutz (forum for recording studioes/engineers/enthusiasts? seemed to have a lot of positive comments on proaudiola, redco, and 1 or 2 others. Proaudiola seemed to be ahair cheaper, so I decided to just go for it.
I don't know if the raw materials from Belden/Canare are more expensive than say Mogami, but pricing on custom cables from Blue Jeans Cables was not competitive when I priced them out.
