IF YOU WANT TO SELL YOURSELF
(1) You are going to have to sell them off piecemeal. Use USAUDIOMART and AUDIOGON for a broader exposure . It’s likely going to take some time, so be prepared. Some may not easily sell if at all, requiring re-listing.
(2) Regardless that they may be new / near new, be further prepared to take a not insignificant haircut on your asking selling price when compared to MSRP new, if you are serious about moving out the pieces . The biggest mistake sellers make is an asking price out of sync with a reality check on what it will take to actually move them out.
(3) Bulk size items shipping strongly predicates an attention to appropriate quality shippers … think FEDEX or DHL or similar. And now in COVID, it will be expensive.,,,quite expensive… ( see #2 above…It immediately reflects in the all-in-cost to buyer.)
IF YOU ENGAGE 3rd PARTY TO LIST AND SELL AS AN AGENT FOR A COMMISSION FEE
Question: do you have someone local who participates and lists on AGON or USAUDIOMART that operates as an intermediary “broker”? He does the spadework and suffers the hassles for a 20% haircut on selling price ?
alternatively, how about contacting a quality local dealer to ask if that Dealer will undertake to advertise and list them as pre-owned on consignment?
