Native DSD support via USB

[Devon]

I bought a Wiim Ultra for DSD files, unfortunately the files downloaded from the DLNA server are converted by Wiim Ultra to PCM 192/24. Is there any way to add full DSD support via USB output? Are there any hardware limitations of the Wiim Ultra or is it just a software issue?

What chip(s) do you think does volume control on the digital data?

This can be done in the es9018 (and possibly others) by controlling how many of the 1 bit converters in the array are activated.

Does that actually do a digital conversion of the original data to a new stream of digital DSD data or is it part of the D to A process?

During the conversion.
i.e. send the dsd stream into the dac but rather than have all 64 1 bit convertors active (all 64 on => max signal) contol how many of the 1 bit convertors are active => digital dsd volume control.

Agreed. I think the original discussion was that you cannot do DSPs or volume control on a DSD file or stream. I think that is the case. During it during a D to A conversion is a different thing. Just wanted to clarify.

There is always only one D/A conversation. And more expensive don't mean better.

And if you try to do that conversion in the WiiM....sorry, No DSD for you. In this case, more expensive means decoding native DSD as it was intended vs converting it to PCM.
