Looking for a plenum-rated balanced cable that won't require a second mortgage

Am currently building a new house, and the architecture will dictate about a 10m run between the preamp location and the amp/speaker location.  Cables will need to run under the floor through the floor joists, so to meet code, they must be plenum-rated.  Looking to run balanced cables with Neutric XLR connections at either end to in-floor AV boxes.  Any recommendations for a good-sounding cable that doesn't cost a fortune?  Could be bulk cable and I'll terminate myself, or could be supplied with terminations.  Would like to keep the cost under $1000 all-in, and less if possible.  Thanks!

I've been using DH Labs Pro Studio bulk interconnect. I needed a 5m balanced connection between my preamp and poweramp, and this works well and sounds great. $11/ft, but they'll email you a discount code for 10% off. 

I'm not sure if it is plenum rated though.

The first thing I would make sure of is that the equipment you are using supports the AES 48 standard.
If so, then any cable with 'plenum-rated' casing should be as good as any other.
If you don't believe me, ask/PM Ralph Karsten (Atmasphere).
The whole point of the balanced standard is to make the cable irrelevant. Ralph sold me my 10m interconnect, I am sure he can recommend something for you.

I've used DH Labs interconnects and have been happy with them, but I don't think they're plenum-rated...

gdnrbob, Thanks for the info, that makes a lot of sense.  I assume I can reach Ralph thru the Atmosphere website?

Make sure your gear supports the balanced standard, else this **might** sound pretty dreadful.

If you’re having a hard time sourcing decent plenum cable just use conduit, then you can use whatever you want. Another advantage of using conduit is that you can add/change cables latter on down the road if need be.

@OP,
As you can see,Ralph has responded. Either PM him or call him directly.
He answers the phone or one of his assistants.
He'll give you all the info you need. Plus, he's a nice guy to talk with.

The cable don’t need to be plenum you can put a run of 1.25’’ corrugated plenum innterduct and run any cable in it
