Use with a Home Theater Receiver

I am considering purchasing a Vanity Pro. However, I'm not sure exactly how it would work with my setup.

I have an Eversolo DMP-A6 streamer which outputs multichannel dsf. Currently, I send this via HDMI to my Denon 4800H home theater receiver, for 5.1 setup sound. It works well but I am looking to further improve the sound quality.

How might the Vanity Pro improve the sound I get from this setup. I would assume it would be connecting to the Eversolo and from there to the Denon.

Attached is an image of the back of the Denon. As you can see it has many HDMi connections.

Could you please provide additional information.

Thanks,

Bruce

Hi Bruce, I have replied to your question on ASR forum, so I just copy paste my answer here too.
The improvement of adding VanityPRO into the signal chain without anything else would depend entirely on the difference between the HDMI audio and digital audio circuit differences and their performance inside your Denon. The reviews of the Denon on the internet (and ASR too) indicate, there doesn't seem to be a lot of a difference in performance between feeding the Denon via HDMI or SPDIF. Also, the Denon might not be able to to process multiple SPDIF inputs at the same time for multichannel config.
If you wish to improve the sound, I would consider to pair the VanityPRO with a decent multichannel DAC and use the analogue inputs of the Denon and use it just as a multichannel amplifier. This way you bypass the Denon's internal DAC and replace it with a higher quality one. You would need to check if the Denon can take multiple analogue inputs for multichannel though.
