Customer service is not only responsive when you call (thanks Brent and Joe), but I just received a call from Brent asking me what I thought of the M60s I received earlier in the week. (I missed the initial call because I was packing up the Athena AS-F2, excellent speakers in their own right, to return because the M60s were the better speakers.) Customer service at Axiom ranks at the top of my list. It's a throw-back to a bygone era.
