There is a lot of desirable gear at welfare records. The Mid-Fi we enjoy on AK and although Glenn didn't see stuff he would want to take home this was the gear that drove the market back then. Not everyone bought the biggest otherwise the Pio SX-1980 would be ubiquitous instead of coveted.
The one price I saw was the 4 chunks of Pio, SA-9800, SG-9800, CT-F1250 and RT-909, all top of the line units for 3k and well a more reasonable retail might be 2/3rds of that maybe there is some wiggle room and a system discount when one buys the speakers. If these units are priced like they were when new and discounted appropriately, then those List Prices are Spot On. Pio gear sold for 1/3 off at the warehouse stores and a bit more at the real stereo stores.
You have to start somewhere on prices and you can never go back up. Good to see a store with gear. Curious as to the work done prior to sale and any after sales concerns.
