30' seems like a whole lotta speaker wire to me. Of course, it sounds like a an excessive amount of IC also. I would urge you to reconsider your equipment layout despite the lights/user interfaces/presence of heavy audio gear at the front of the room.
One of the things we audio-junkies have to contend with is the dreaded SAF, also known as the "Spouse Acceptance Factor". There is often no way to get around bulky equipment and wires lying visibly on the floor if one hopes to achieve the highest possible sound quality from their gear. But getting high sound quality from you current gear sure beats going out and pi$$ing away another 5 large on more refined equipment just to obtain the SQ that you already can by simply compromising on the SAF.
My listening room is my living room, and its somewhat unconventional looking due to the compromises made in the pursuit of SQ. It is still a cozy place for family gathering and watching the occasional DVD with the family, but the space between the listening chair and the Logans is an exclusion area -- no furniture, coffee tables, toys, junk, goofing off, horseplay, grab-a$$ing or food allowed. The wife ain't big on that aspect, but she puts up with me and my idiosyncrasies...
But back the the wire issues, specifically..... My ICs are also custom lengths and long by most standards -- 16' RCA type, but they are solid core and double shielded. Having the power amps directly behind each speaker and utilizing two runs of 5' speaker cable works for me. It should be noted that long IC/short SW sounds
slightly different than short IC/long SW. I went the route that i thought sounded best. I recommend that you experiment with both methods and decide for yourself, but ultimately... less wire to screw up your sound is a better thing.
Sorry for the long response
