Re: House Rewiring (Data and Power)

[Chris Hunter <cjhunter@xxxxxxxxxxxx>]

For audio, I'd keep speaker cables as short as possible ... if
distances have to be covered, do it with balanced lines between pre-
amp & main-amp ... we've done that where we are now & the
difference
is clear !  Speaker cables need to be big in any case & tend to be
expensive, too.
