Is there an affordable long run XLR preamp to amp cable out there?


I'm currently using a pair of Oyaide Tunami XLR cables between my preamp and amplifier(s). I'd love to get an affordable pair of XLR cables to use with other amps 20 feet away, eliminating a need to have 2 complete set ups. No deep pockets here... are there any affordable, good sounding long run XLR preamp to amp cable out there?

Chances are the sound signals of any recording you play ran through hundreds of feet of Mogami at multiple stages.
Mogami, Belden and Canare are all used on stage and studio. My bet no one knows how many miles are out there and which one is used the most... my guess Belden or a knock off cheaper generic. The three noted are all good but have their limitations. 
I just mixed a live concert using a 100 foot snake and, as usual, it sounded great with no limitations. 
I agree with the Canare microphone cable recommendation above. I had HAVE, Inc. assemble a set balanced IC's (~15' lengths) with premium grade Nuetrik XLR connectors at a decent price.
I’m very happy with 25-foot cables made with Mogami W2549 and Neutrik XLRs, put together to order by Pro Audio LA. (I think the pair ran $105, including freight.) I recently auditioned some "audiophile" $2200 cables and they were not nearly as good sounding as the Mogami cable.

These run between preamp and amp in my system.

Tip: Most pro audio shops (including the one listed) can put red rings onto the XLRs of one cable for only a couple of bucks more.
