Lokie-Spending $1,799.00 on a Converter, that would normally sound great; but, sounds awful due to compatibility problems with DAC IS a waste of time and money. Turning this into Russian Roulete, or Crap Shoot is
never more simple, and definitely more complicated. There is absolutely nothing wrong with any one of these Converters, except they will benefit certain DACs; but,
not others. The critical factor is the design, and type of
DAC, the optimum Input based on that design, not to mention the Power Supply for the DAC. All DACs are nowhere
near the same, and not all Converters will behave the same
with all DACs-no matter what the price or quality. Some get
best Sound Quality with Firewire, others with USB, some
with Fiber Optic, Wireless, SPDIF, BNC, AES/EBU. They can't
be all optimized for best sound quality for all DACs, that
would be impossible. The only deciding factor here is the
design of the DAC, and the optimized Input based on that
design. This will limit what Input to use, limit what
Converter to use, and which type of connector. Process of
elimination doesn't make things more complicated, guessing in the dark does! Try Halide Bridge before you buy, if you
want to make things simple. If you even want to make things
more simple, do a little research on your DAC. Wonderful thing the Internet, saves time and money! Do a search on
Reimyo DAP-777, who knows what you might find out.
Knowledge is Power, lack of it is never simple!
