Dan_ed, so you must be the guy I see walking by with the PC on his shoulder, pressed up to your ear? A boombox for the new millenium, I presume?
My father has taken great interest in this thread, and wanted me to share his latest innovation. It still requires the use of one amp, but he's got the entire house now wired (or strung, as it were) for sound. You see, during the remodel, he had the electricians run a 16ga string equivalent throughout the house, and into five separate rooms, thus allowing him to place four of his amplifiers up for sale right here on the 'Gon. A prize to anyone who can pick them out of the classifieds.
Given the complexity of the network, he opted to use a bucket at the home base amp in lieu of the more customary cup. But now, whenever he wants music, he can pick up the cup hanging on the wall in any of the five rooms, hold it to his ear, and take in the tunes. In addition, he can simultaneously use the cellphone on the other ear for a sort of Cecil Taylor-ish stereo effect. He did say that the cats must be sequestered during the string--he used Litz, by the way--installation process, or they will invariably become permanent wall-dwellers. Unfortunately, Mingus the Persian now must be fed through the light socket in the guest bedroom, poor little guy.
