I had a Zon Hyperbass for a while. I bought it used, but it was still significantly more than that.
IIRC they are about 7 grand new.
These days I’m very happy with my Sandbergs, but I do have a hankering to get another Marleaux one day. Probably pushing 4K these days for the spec I’d have. But worth it. Amazing workmanship.
Now I’m paying for kids at university the chances are very slim!
