Refurbished Bluesound Vault 2

Has anyone purchased a refurbished unit from Bluesound? They have the previous models discounted so curious if they’re actual returned used units of inventory left over. Price savings on the Vault of $400 off doesn’t make sense if I’m going to use another DAC to spend the difference for the current.  $400 isn’t going to break the bank so if anyone has an opinion to spend the money and buy the current unit please share.

Thanks
