Thank you to all of you who've responded with advice about shipping and the Sonos hook-up. I see why Tom was so appreciative of Audiogon. Its users are a very helpful and kind bunch. It's really a wonderful little (well, perhaps not so little) community.
Tom kept the original boxes for all the equipment. And we had everything crated, anyway, when we moved from Chicago to Palm Springs. The "local pick-up only" advice is good, though I supposed it will limit the pool of buyers. But it's not as if I have to get rid of things right away. They can wait for the right buyer.
And speaking of breakage during shipping. Yes, when we moved, despite them being in original boxes and being crated, the movers actually broke the glass on the front of the preamp. Tom looked into getting it repaired, but I don't remember why that didn't happen. Perhaps because he'd have had to ship it to Macintosh, and there's the Catch-22. Anyway, the preamp has a crack in the glass. Not sure how that affects selling it, though if I can use it for the turntable I won't be selling it anyway.
Again, many thanks to all of you who've responded. I very much appreciate your kindness and help.
