Hi , The prior Nagra HD DAC had Amanero USB interface, but cannot find what USB interface the newer Tube DAC has...will XDMS new software work with Nagra Tube DAC USB input? Thx for any advice...Indeed, our USB driver cannot support the Amanero interface, you can still change buffersizes using the driver supplied by Amanero but with a much more limited adjustment range.
The bottom line is you can use a DAC with an Amanero interface just fine but you will then lack a few more advanced SQ enhancing options which our own USB driver provides.
XDMS only supports USB, AES/EBU, SPDIF. For networked endpoints it only supports those sporting a network ASIO driver like RAVENNA (Merging DACs).
