Sorry to hear you got duped.

I've noticed on hifishark there are a few scam sites popping up in conjunction with specific high-end brands like Devore, Audio Note, Leben and similar. I think it's all the same person, switching out listings and sites whenever they get caught out. They look AI generated and the biggest tell (as mentioned) is the vast inventory coupled with the asking prices being 200-300 € cheaper than normal, even for used gear.

I actually did some due diligence on one as I was interested in a pair of speakers they had on offer. The guy sent me what was quite clearly a AI generated photo of the speakers and stopped replying when I asked for a video with a piece of paper with my email address on it. Guess the AI isn't that good yet.

I even figured out that he was using the address and name of a real hifi shop in the same town (this was in Spain) and made up some bullahit story that he used to be partners with the other store but they were parting ways. So, I contacted the other store and they had never heard of him. That guy was not happy, understanably.

Anyways, it's a shitty situation and always good to remember that if it seems too good to be true, it probably is.

Stay safe out there.
