that is kind of the grey area i was talking about, especially when it comes to old school equipment, where only a hand-full of people, sometimes not including the seller, knows much about it...... just getting back into c.a., that's pretty much where my experience comes from, with some hobbyist knolwedge of things between now and then..... for exaple, not an ideal example, but still- i just saw a jbl 6k amp from 2004, and provided my experience with it when it was new, in response to the o.p. mentioning "i don't think people really know what this is"......... is that so bad, as to ban someone?
