Hi Pavel,
I received my unit on Thursday and have been using it the last couple days. It has the latest firmware and the multichannel XLR output board. So far I haven’t experienced the dropout issues reported by others with the previous version of the firmware.

My setup is described briefly below.

Blu-ray player {configured to output LPCM and for SACDs, DSD} >> VanityPro >> Okto DAC8 Pro

In my listening tests so far I’ve had the VanityPro configured to convert DSD to PCM with 176.4 KHz output sample rate and using the Slow HB filter.

I tested a mix of DVD-Audio and SACD stereo and multichannel discs. My SACDs and DVD/Blu-ray audio discs now sound pretty good when played from my Blu-ray player. I’ll have to do a proper A/B comparison but I think it sounds pretty close in quality to what I get when I stream the DSD and FLAC files direct to my DAC over USB.

However I think I may have identified a bug in the SACD 4.0 downmix implementation. I observed the following:

With 4.0 music in a 5.1 container ( so LFE and C are empty) the downmix output is stereo instead of a 6dB lower version of the quad input

With 5.0 music in a 5.1 container ( LFE empty) the downmix output only has content in FL , FR and C instead of a true 4.0 output

With 3.0 music in a 5.1 container ( LFE, SL and SR empty) the downmix output only has content in FL , FR and C instead of a true 4.0 output . Also I can tell that the center channel wasn’t added to the front left and right channels as the vocals on this album are all in the center channel and that remains the case when the downmix mode is enabled.

So it looks like the downmix formula in the manual is not being applied and it simply drops the rear channels when this mode is activated. Please fix this in the next firmware release.

Otherwise, this is a fantastic unit and I’m very satisfied with my purchase.

Thanks,
Esosa

Hi Esosa,
Thanks a lot for your feedback! I am glad to hear that you are happy with the product. The dropouts should not happen any more with the new firmware even without adjusting the DPLL setting of the ESS DAC in the OKTO, so thanks for confirming that. We will have a look into the 4.0 downmix function. Should you have more feedback or comments, don't hesitate to share!
Thanks again!
Best Regards,
Pavel

HDCP doesn't seem relevant for audio. I have the Vanity Pro working well with Roon Labs and Jriver. Sound quality is superb.

Hi Esosa,
I have checked the DSD 4.0 downmix algorithm and it is indeed messed up a little. It is now the surround channels instead of LFE and Center that get mixed with the front channels, while the FLE and Center are thrown away. Thanks for flagging this up, it will get fixed in the next firmware version.
Best Regards,
Pavel
