Suggestion on IN WALL XLR interconnect

If there is such a thing. I need 40 ft of XLR to put in wall to connect preamp to amp. Anyone has any suggestions on what I should get? Thanks shenzhi
i'd not myself bury any interconnect in walls. if possible, you might think of installing fairly large plastic conduit in the wall so that replacements might be made in the future. for your application, i'd recommend cardas neutral reference. it really does work in long runs. i use a 21' pair (balanced) between pre and amp in my system.
Transparent makes specific interconnects for in wall applications. See Hope that helps...
