thanks for your amazing comments, sharing a lot of valuable first hand experience.
Yes, the second hand value of Directstream is very low, but official prices are always ridiculous in this business and I thought it was something normal.
@dlcockrum ,
after reading @in_shore comments I took a look at the Denafrips page. Needless to say, the Terminator looks terrific: isolation, thick metal, very nice modular board, linear power supply, full of pictures showing what's inside. All the basic checks passed. It does not look like the typical garage audiophile product.
However,.... sorry, I don't trust any Chinese thing without western support and warranty. The info they provide about themselves in the site is vaporware, not address or names to send the police if the thing burns the house.
