Thanks for the update!

I have no use for DSD. I would use Ethernet and SPDIF.

I'm still looking forward to hearing this DAC.

Listened last night to 44.1 and 96 tracks.  My wife and I both agree that it beats the Overdrive for vocal liveness using my Music First passive line stage.  For bass and slam, the jury is still out, but may be limited by the line stage transformers.  Really smooth natural vocals.

Still a lot of work to do and money to spend to get it in final form, ready for sale.  I should have a proto to send around before that though.

Tried native DSD64 yesterday with the Ethernet interface.  Amazing sound quality using Linn Kinsky.  I have the same track 24/96 and DSD64 and the DSD beats the PCM hands-down.  More clear, less echo noise, superb bass.  No overhang.  Great attack and decay.  I've never been a fan of SACD, but this is something else.  Very exciting!!

I plan to download some HDtracks DSF files today and try some tracks that I'm more familiar with.

USB license for DoP is another problem.  At least with Audirvana, it is not showing DSD capable.....

You mentioned Roon compatible. Also DLNA? Are there any other ethernet streaming protocols?
thanks

Yes, it does DLNA, UPnP and Open Home. I don't know of any other protocols.

I determined that the USB interface can only do DoP, but I have not tested this yet.

The Ethernet can do both DSD64 and DSD128 now.  Cannot do DSD256 because the D/A chip does not support it.  I decided it needed DSD128 because many of the downloaded tracks are only available in 128 and 256.

Still 70 style, but less GI Joe.  :thumb:

Glad you kept the red button.

Richidoo - thanks.  I have had a lot of feedback and made some changes as a result.  I try to listen to what customers prefer.

I made some progress on the DSD and now it should support both 64 and 128 natively using the Ethernet interface.  Still getting the signal timing ironed-out to make the D/A chip happy.
