Osborn and ESL57addict, sad to say I also have recently had a similar experience with Wayne Picquet at Quads Unlimited this year.
I sent him my speakers in February 2020, and promptly paid him $3400, only to be met by radio silence, followed by random excuses (see above health issues, no grandmothers, but this time dog dying).
When I found your above posts, I feared the worst and triggered PayPal Buyer Protection to get my money back. Now he has my speakers - which frankly I would let go, but I inherited them from my father, so they have sentimental value.
I am not sure how to proceed, but if it would help, perhaps co-ordinating our efforts (Class Action, etc) may help.
Suffice it to say, I recommend any ESL owner not do business with Wayne Picquet.Thanks to all those on the forum - these are truly amazing speakers.
