Thanks guys - very much appreciate the input. I wonder, too, John about just how much extension that K100-SW will provide.

BTW, I used to be around here back when I first got my M80s - that username and password now long forgotten... ;-(

I got the M80s originally in part due to having such good bass response that a sub would not be 'necessary'. And in truth I haven't really felt the need for one. But every so ofter I get into the 'what about a sub' loop - so, I'm kind of off on a whim here - may be that this Klipsch unit really brings nothing that I'm after to the party (at $150 my expectations are not high). Again, I'm after musicality not Armageddon. We shall see.

The EP350 is what I lust for. Turning 60 tomorrow - a worthy birthday present from me to me, perhaps! ;-)

Thank you both again for the thoughtful replies!

Steve
