Do I still need a DDC in between?


This is my current rig:

Wiim Ultra (DH Labs Mirage / Cardas Clear USB, 0.5m) → Gustard U18 (DH Labs HDMI 2.1, 0.5m) → Harmony μDAC (Mogami quad XLR) → Parasound A23 (Belden 5T00UP) → Wharfedale Linton

The sound is very good to my ears—excellent tonality, detail, and especially soundstage, with impressive height and depth. However, I’m considering trying the Volumio Rivo Plus released recently, which offers an I²S-over-HDMI connection.

My question is: would I still need the DDC (i.e., Gustard U18) in between, or would a direct I²S connection from the Rivo+ to the Harmony μDAC deliver comparable or even better sound quality? Have you had any direct or similar experience with this kind of setup? Any advice would be appreciated.

@mattw73 I was using a Ugreen before the LanShack. Hopefully you will perceive the improvement I did.

This time, I’m not sure if I hear a discernible difference. In any case, both are better than the unshielded Cat 5e. The cable is beefy and well-constructed—just a bit stiff due to the solid conductors.  Nevertheless, I will possibly ’downgrade’ to Cat 6A, which uses a maximum bandwidth frequency of 500 MHz, instead of 2000 MHz on cat 8, as the latter is more prone to EMI/RFI if not properly grounded on one end. LanShack offers cables with similar specifications.

@lanx0003 well I think both cables are properly shielded..I guess the solid core didn't make a difference. In my case the Lanshack was shorter than the Ugreen. But any benefits I perceived between the 2 could very well be mind games. At least none of these cables are expensive. And yes, you lose some flexibility with solid core conductor cable. 

As you know going to Cat6 is not really a downgrade. Cat8 is well beyond what is needed. I went that route with the Lanshack as it seemed like it's the best (overkill) LAN cable they offered. It does lack the gold though. Oh yeah, the one you posted is the exact one I went with. 

@mattw73  Some one confirms that frequency is determined by data speed and I think Cat 8 cable is not noisier (than cat 6) that produces more EMI/RFI.  There is alot misinfor. out there.  

@lanx0003 I agree that there is a lot of contradictory information out there on various topics. Im a little ignorant when it comes to digital/streaming so misinformation in that arena can really set me back lol. 

Side Note- I ordered a Laiv uDac today. Still have my Pontus 15th but I've been wanting to get a feel of a different R2R..I wanted to try the micro dac. Especially after you personally preferred it over your D90 III.
