Hi Bryce,

The setting that the Katana driver exposes if DoP ON/OFF.

Whats DoP sync/async? Do you have a link that explains the feature?

Hi Tim, 

Sync/async is an ess9038q2m parameter. I was not able to find a good link that describes the feature, but it is discussed on some of the diyaudio forums. In looking for the link I found the answer to my question in a post from cdsgames: 

Enter Synch mode with Katana. Why use dPLL at all on ess9038q2m ? Our clocks are clean so we use a little trick called SYNCH mode where dPLL is bypassed . Direct clocks no added sauce . Dpll setting = 0

Makes sense right ? Hold on, electronics are never simple. Enter DOP. DOP is not supported in synch mode.

Behind the scenes we implemented a very sophisticated driver that sw betwen asynch (dop) and synch (pcm). 

So it seems that DoP ON/OFF also switches sync/async.

Cheers.

Synch asynch is done automatically in firmware

There is a bug in the Katana config in moOde 4.2. It won't be fixed untill release of moOde 4.3 and the 4.2 --> 4.3 update. Timeframe is TBD.

Thanks for your quick reply. I try Volumio newest version and it is better, and have some filter of DSP. But I'm a fan of Moode.

moOde 4.3 provides access to Katana DSP

Release will prolly be just ahead of the Katana hardware updates that Allo is working on :-)

Katana 1.2 should start shipping in about 1 week

We improved further THD+N. "Fatiguing sound" that was present on some smaller speakers is completely gone with optimization of the LPF on analog stage.

Thx to all for your patience. We appreciate our customers and anyone that has a Katana will received a free isolator along with a new Katana 1.2

Readings of old Katana were published at audiosciencereview by Amir https://www.audiosciencereview.com/forum...dacs.4164/

Note that only DACs that beat Katana are worth 1.5K or more.

Last thing, all reviewers will get a new Katana 1.2 (Thx you Tim for your time and effort)
