The KEF's are KEFKIT III's, essentially kit versions of the Concerto, a very nice speaker, and components are worthy. Theres a couple of inline JBL L100's with missing mids, also a couple of corner horn type speakers under the big Sony box that might be worth checking out, look a bit rough though. Some nice Marantz, Pioneer and other receivers. No telling what might be in all the USPS boxes, maybe the tubes?
I sort of wonder what the black backed, stacked on top of each other speakers are, sort of look like either Altec 14 or 19's if you're lucky, maybe some Speakerlab versions, being in PNW?
Also looks to be a Sansui 8080 or 9090 under a Pioneer SX1050 or earlier 828, along with some later SX950 types on the floor. I'll bet there are a few Klipsch in there somewhere along with a few tube testers.
Also, looks like maybe theres the top of a Martin Logan speaker in one pic on the left?
