Innuos Zenith mk3 complete disappointment

I have the following setup: Accuphase e480 with dac50 module, Magico A3, Chord SarumT speaker cables, Node2i a streamer only as I use Accuphase's day module. Chord Anthem bnc cable between Node and dac. (ethernet connection to streamer). I also have PSU mod for my Node2i.
I had opportunity to test Innuos Zenith mk3 during this week in my system. The same ethernet connection was used. From Innuos to dac I used entry level USB cable. 

I used Qobuz through Roon in Zenith and through BluOS in Node when testing. From the start Zenith sounded flat compared to Node2 and more I went through different music it became apparent that dynamic range was not on same level as with Node2. Especially the lower bass took a big hit compared to Node.  I also tested some highres music files with Roon and it was shocking to hear DSD with Zenith. PCM was "normal", but DSD was completely muffled, it was like hearing the music from the other room. One of the DSD records I tested was Temporary Circumstances - Clandestine Amigo (PS Audio - DSD64).

With Zenith all the testing I did was with the Roon, as iPeng client which I also tried was utter rubbish. I tried to level the sound volumes with iPhone app, but don't know how good job it did. For me Zenith was a complete disappointment from the sound quality point of view. Roon is Roon and I like it, but I think iPeng client is not on suitable level for the high end device like this. 
The problems with Zenith could be caused of course by my system: dac module on Accuphase or for example USB cable. Still I'm shocked how uninteresting sonically Zenith was compared to Node2i, as from price point of view it should be other way round.

Clearly your experience is not typical, and signifies that something is not right.  I highly doubt that the USB cable is at fault (although a good cable can help get the most from a component).  
I have owned the Zenith Mk3 for almost two years and have never had any issues with its sound quality.  I have had some software related issues that were quickly resolved by their service tech (remotely, I should add).  
It would be worthwhile contacting them to ask for their take on this before you give up on it.  It's not out of the question that your unit has a problem that explains the poor SQ.

The following is reply from Innuos related to the problem. I’m using default settings for the Roon, which are enabled when Roon core is enabled in Zenith’s settings. I’m really disapointed to the way everyone involved (vendor and Innuos itself) are avoiding to take responsibility even with Roon which is integral part of their product. If this is what happens before purchasing decision, what happens to their support after the sales. Innuos should be highend product vendor, but based on what I have seen so far is far from that, no remote troubleshooting, no device log collection, it seems they have no way of analyzing what’s happening with the device. 

”The customer should firstly make sure that the ZENith is on the latest 1.4.6 as this has a few key engine upgrades. Most importantly though, it includes new options in the DSD section of my.innuos.com -> Settings.

The customer should try out the different modes available to see if there is any difference.

Ideally, the ‘Native DSD’ should be the one to use, but it is also worth testing the ‘DSD over PCM – DoP’ and maybe even the ‘Transcode to FLAC’ which will change the stream to a 32bit DXD format.

Do note that these options only apply when using iPeng & Squeezelite to playback from the server – when in Roon Core mode, it has its own DSD behaviour. In the case of Roon, I would also suggest using the normal Roon Core mode and NOT the experimental Squeeze version. I’d also make sure all the Roon DSP is turned off, any Upsampling/Oversampling etc.”

One more update, I transfered Roon core to my laptop and tested with direct USB connection to Accuphase’s dac with the same cable. Sound quality was as expected, so no problems with USB connectivity on dac50. Based on this, I would say that Innuos Zenith with Roon has problems with DSD, is it the device or some wider problem with the latest software version (1.46) impossible to say.
