I don't quite get the 'don't bother' posts. It's not like it takes hours of work to do a little test run of "biamping" one's speakers. Like I said, if you've got the extra cables lying around (who doesn't?), the extra channels, and bi-ampable speakers, why not try it? This isn't like getting a tattoo or joining a cult (some might disagree
). I consider 'tinkering' to be part of the great hobby of home audio. Perhaps others do not, and that's totally cool.
<Forest Gump> Like my momma always used to say about tryin' new foods, "you won't know you don't like it until you try it". </Forest Gump>
It's also easy enough to bi-amp just one speaker. Then you can fiddle with the balance to see if you could tell a difference, L to R.
Good luck, have fun, and do try it out. Let us know how it goes.
