Excessive and unnecessary or no, I want magnetically shielded speakers. @EOF. 
 
I have never used Audiogon before.  I just initiated the registration process with them, which can take up to one business day, apparently.  I see two sets of Quad 12L actives for sale on there, both are about $800/offer: 
 
Pair one: gloss black, ~5 hours of use.  Probably demos.  This sell was recommended to me by a fellow head-caser. 
 
Pair two: gloss black, NIB, comes with warranty(?) 
 
I have, uh, never made an offer on an auction site before.  As a new user with zero feedback, am I out of line to offer, say, $650 for a pair?
