Hmmmm ….I don’t have a dog in this fight , so I’m taking a wild guess here that you may have lost him here:
” …. They’ve been packed up for some time apparently. On April 27th, I emailed, simply asking if he’s run them lately just to make sure they are ok...”
SELLER may have taken umbrage (…rightly or wrongly….) at any challenge to his reputation/feedback that it could be inferior or somehow damaged goods being offered in the first part:
…. and/or ….
it’s simply not worth his time nor effort to drag them out of storage, set them up, and report back to you singularly, for an effort creating a duplicity when his ad would have properly and accurately already reflected their position condition
His attitudes may have been favourably improved upon receipt of a modest cash deposit with your late query …He may have lumped you in unfairly by doubting your commitment, predicated on his reminiscences of prior bad experiences by “ tire kicker” parties . In these audio forums, these irritating types DO walk among us,
of course, it’s also plausible that his reported unit condition was say, “…a little casual with the truth ,” ….. .and your request for express written confirmation would have further strained that position….so he now ghosted you.
just sayin’.
