I just finished installing my first HT system and it everything is working perfectly. I'm a little on the obsessive side though so here is my question: For the front speakers (all speakers are Sony SA-VE 335. Not exactly audiophile quality but good enough until I upgrade down the road)I have mounted them on stands with the cable concealed inside the stand poles. No problem there. The rear speakers are a problem however as I had to mount them behind and on either side of a couch, about halfway up the room's rear wall. The speakers themselves are silver-colored and do not lok bad on the wall, but the problem is that I have a cable running up the wall to each speaker. I can't hide the cables in the corners of the room and I can't drill holes in the walls and run in-wall cable, so my question (finally!) is what cable can I use to run to the rear speakers that will blend with the wall. I've seen monster's Flat Cable but It doesn't have an adhesive back and is heavy, making it tough to run up and fasten to the walls. AR has a microflat cable but it's 18 gauge. Is that too low a quality for 25-30 foot runs? My plan is (unless you have other suggestions) to run flat cable up the wall to the rears and then paint it to blend with the wall. Is this adequate? Any other options?
