OP have you actually heard the Tambaqui? A friend has one and IMO it was nothing special, I've heard better. He also hasn't been thrilled with it and might be looking for something else.
Odd DAC Pricing
I’m in the market for a Mola Mola Tambaqui and I’ve noticed that many listed for sale are of recent manufacture and only owned by the seller for a few months, yet they are reselling many thousands below retail. How can it be that an item that retails for $13,500 is so often resold only months later for $4000- $5000 off. Sometimes the reseller is already the second owner in just 6-9 months. Is there something I don’t know? Some gray market? If you know something about how these are purchased that you can’t share publicly please DM me. Thanks for any information.
