I'm willing to spend upto $2k or so on new speakers (currently) that'd last me at least 20 years or so, used not even close just due to the reduced lifespan I'd have them for (as well as the warranty on them no longer being valid). (I realize some speakers can last much much longer than that amount, but unfortunately others don't, especially when buying used I have no idea how they were treated prior)
I'd rather have something nice and last 20+ years and have to buy my system piece wise over the next year or 2 than to get something just to replace in a few years when more cash comes around. But I was thinking that the reference 7 series would be a good snag if I could get them for a great price.
I'm more into the tall tower type speakers than the boxy ones (for fronts).
