Sony HAP-ZIES HDD player is it only 16bit 320kbps native playback ?

I run my HAP in to a Vinnie Rossi LIO with DAC 2 module and the display always shows the native resolution of the original file (does not show bit depth though). The Sony does not upsample through the USB output ( I wish it would allow the DSD resolution upsampling option through the USB output. This is only available via analogue line outputs).

Something wierd goin' on with your setup.

Check the player settings. It may be set to limit the output.

Dear All...thank you very much for making time to answer my query... Really appreciate it Y’all !

However my problem still persists. I did check all the settings on Sony. And tried contacting Sony support but no response. 
I consider myself super tech in this regard and I will humbly accept anyone keen on pointing out my ignorance. I want to keep this stellar device for long because I am really enjoying the music for a change. 

Problem : When Sony usb is connected and engaged  to an external Dac the display shows 16bit 320kbps regardless of higher formats played. Even when listening to the Sony’s internal dac outputted to its own rca / xlr , the sound to my hi tech pro ears, still tells me, on blind testing that it sounds 16bit 320kbps.  And it sounds bloody marvelous In 16bit 320 kbps too after approx 300 plus hours of play. 
I am convinced the Sony is capably playing Hi-Res formats internally from its hard drive or when pulled over the network and then compressing or downsampling the formats bandwidth, to play finally in 16bit /320kbps either at its  rca / xlr or usb terminals..

My Delusion : This makes sense from an engineering point of view as compression puts let’s stress on processing, chips and cooling when working or resolving with big  hi rez formats. Compression on the fly, works the processor,  not dac and ram or bus channel outputs .  

And from Sony’s point of view as long as it sounds great even compressed  and keeps cost down with good profits then why not ? I read somewhere too on Audio-quest forums that they claim higher rez formats sound glorious when downsampled. This they do with their Dacs  Cobalt / Red / Black all maxing out at 24bit/ 96khz even though they load, analyse and process higher stream formats like MQA, Tidal, Apple, minus DSD formats.  And again to my ears the  down sampling techniques used by AudioQuest & Sony kills & thrills my ears over my other boutique units listed below in my home and recording studios.

To me it sounds like the Mytek might be downsampling.  I used to own a Mytek and there are a heck of a lot of options in those knobs.
why not just play the Sony using it own DAC and then you won’t have Audiophilia Nervosa?

Oops, I just noticed you said it happens with the Chord as well.
