Would a DDC (Denafrips Iris) improve my system?

Hi, 

In reading various threads, stumbled across those recommending introducing a DDC to a digital chain when using USB.  I’ve got a U2mini with S/Booster feeding a PS Audio Direct Stream MKii.  I flip between using a USB connection and AES connection between the Lumin and PS Audio MKii.  Many say the best input stage for the MKii is the i2s which my Lumin doesn’t offer. 
 

Any advice on if something like the Denafrips Iris would provide a noticeable improvement?  The option of being able to try the i2s input on the MKii with out having to change my streamer is what’s intriguing to me.  Flip side is the Lumin and PS gear are both solid prices of gear, I would be surprised if they “needed” the Iris in the middle of the chain to scrub, further clean up the USB signal but I’ve got no knowledge or experience with that so might be off base with that thought. 
 

Thanks in advance for some advice, guidance.

Hi.

I used the Iris in front of a Denafrips Pontus II and Venus II taking the USB output of a Ifi Zen Stream to I2S output. Definitely made an improvement. But, I think if you find a high quality streamer with I2S output built in, the Iris wouldn't make much difference (speculative). I now have a PS Airlens that I put into my Venus II and it sounds at least as good as the Zen Stream + Iris configuration but without all the hassles of the Zen stream and additional boxes and cables.

My two cents.
