What condition are the speakers/receiver in? Do you have original boxes, manuals, etc.? I can put a guesstimate assuming NIB condition, (if not, reduce by 20-40%)
Monitor 9: $700/pair
Studio CC 470: $500
Monitor ADP 190: $200/pair
PDR 10: $200
RX-V2500: $350 (need to have remote, power chord and mic in original box)
