$1.5K is too much. Indeed individually sold, the components, if in excellent shape, may bring in the total amount... but even then, I doubt it. Is it all in a Pioneer rack?
pl-630 tt - $150
tx-7800 tuner - $100
sa-8800 amp - $250
sg-9500 eq - $100
rt 707 rtr - $200
ct f950 - $200
So there's a grand and all of these are high end of my estimated prices. Prices, that us cheap bastards would likely never pay, unless we're completing a collection or the item was NIB.
I can happily be corrected if I'm off.
