Thanks. After some further review the listing was indeed too good to be true: DSP8000.2 on www.audio-markt.de

Advert-ID: 4954111280

The asking price of EUR 9,000 was reason of concern and after some back and forth (e.g. his wife worked at DHL and could arrange for nearly free shipping and his idea to use an escrow company (www.essescrow.com) it was clear that this was a scam. I will post pictures from the listing at audio-markt.de and from a drop box folder the seller shared with me. You will notice that the speakers are different. If you see these pictures again in a listing this should give rise to concerns.
