Do you really want to use metal conduit for cables to and from each light switch and outlet? Do you think that this really could be a serious weak point in your new studio? Anything else in your chain of used gear is without weak points? Consider to ask on audio engineer forums and read more than one paper. Unless you shouldn't be Ri¢hie Ri¢h, you perhaps want to spend time and money in something that might improve acoustic properties, audio gear or music instruments. That is at least what I would do. 2 Cents, Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
