To be clear on one point in my previous post, for RJ45, I am only referring to an RJ45 cable inserted between the Denafrips DDC and the Denafrips DAC. For RJ45 cables placed elsewhere in the system, the length is not an issue.

Hi Blake,
Noted and will try using available 0.5m and 1m yellow cat 8 ethernet from Hermes to TP via i2s-C lvdcmos to try against dual aes-ebu to report back any pop and difference in sound quality then.
But as mentioned, I am using only ddc for non dsd source of bel canto fm tuner with Antipodes direct to TP via usb and do not expect better sound quality with only available i2s-C when back to 96khz like hdmi i2s vs dual AES at 192khz.
Cheers.
Richard
Hi Blake,
0.5m yellow chinese ofc cat 8 cable works fine without pops or any abnormalities with 96khz Bel Canto tuner from Hermes to TP via i2s-c lvcmos Rj45 ....
It is more airy and relaxed sounding but slightly less detailed and dynamic as compared to i2s-b lvds RJ45 on the same attributes and also when compared to dual aes-ebu that I prefers.
Using aes-ebu as a reference and better or worse depends on your preference and music genre, it will be aribitrarily and relatively as below on clarity, details, focus and dynamics to me via both Revel Salon 2 speakers and Grado FG-1 headphones:
Dual aes-ebu=100%
I2s-b = 50%
I2s-c = 25%
This also tells me that you do not need an expensive silver Tubulus hdmi i2s cable if you wish for more airy relaxed sound with i2s-c lvcmos RJ45 via shared cheap ofc chinese cat 8 cable .. system dependent YMMV as usual.
Cheers.

I was reading the TP manual and it says the 5v is needed to trigger the USB input on, apparently the USB is turned off if it is not used to lower noise.
I remember I had early issues when I ran several servers with one that had I2S out, if I changed input between USB and I2S and then back to USB I would need to restart my USB server to retrigger the USB to turn on after leaving it. I wonder if I need the 5v trigger now with the Iris.
Hi Rikki,
Glad I did not read the TP manual then as it works unless idefender3.0 does not cut 5v which is highly unlikely the case and I do not connect external 5v to it.
Read the manual now and it simply says the below which to me means that the usb is in fact self-powered when you select usb input of the TP:
NOTE: The USB Module is designed to trigger on only when USB Input is selected. This is intended design to reduce digital input interfaces cross-interference for best sound reproduction.
Your mentioned server case is more likely that it needed to sense that a dac is connect else it lost connection which I too had experience with other usb source and not TP or Terminator itself.
Try it, it is only usd50 in the crazy world of audiophile and it certainly doing something in a positive way even for the Antipodes cx+ex stack.
Cheers.

Hi Richard, I got this from the denafrips FAQ page under USB
DENAFRIPS DAC USB module is powered by its internal regulated, low noise, low ripple, high speed linear power supply.
However, it needs the USB cable to supply the +5vdc as a logic signal to trigger the internal power supply to the USB module. This design is intentional for best sound quality consideration.
I use the I2S input now. I do have a USB cable between the Statement and Iris, I don't know if the Iris needs a 5v signal.

Hi Rikki,
Will test output of idefender3.0 to confirm then but indeed not sure of Iris while Hermes certainly work also in my case in addition to TP.
Then I can sue ifi is indeed idefender3.0 still has 5v output .. keke !
Cheers.

I had a Yggy and there is no comparison to the Terminator or TP, the are just in another league. The difference is reflected in the price just as the difference between the Terminator and TP are reflected in their prices.
I still have an Yggy A2 and also a TP (which replaced a Terminator). I agree that the Denafrips DACs are a nice step up from the Yggy although the Yggy is a very nice DAC in its price range. I haven't heard the Venus or Pontus so not sure how Denafrips' comparably priced DACs compared to the Yggy.
The Termy and TP benefitted greatly from adding the Gaia. That took them to another level (I actually haven't tried the TP without it but I'm assuming the improvements to the TP are similar to the Termy.

On the Terminator (which doesn't have clock outputs), adding the Gaia and switching to i2s was huge, but the Gaia clocks are probably better than the Terminator clocks, which can't be said about the TP. So when you connect the TP clocks to the DDC, you're using the TP's clocks.
I suspect the Gaia would be a better choice for the Terminator, but the Iris (using the TP's clocks) probably achieves the same results with the TP.

Hi Rikki,
I find this depends on the quality of your source to denafrips dcc to TP or directly to TP ....
Just try 10x swapping usb output from the Antipodes EX+CX stack to the Hermes clocked to TP and direct to TP and selecting dual aes, i2s-A hdmi and i2s-C and direct usb on the TP.
Direct to TP sounded refined, polished and natural while via Hermes sounded like indeed boosted thru some EQ especially via dual aes although it sounded better than i2s-A and i2s-C in that it is more in focus and dynamic.
I only have my Bel Canto fm1 tuner via aes-ebu to the Hermes that indeed sounded better than direct to TP .. probably benefitting from synced to single TP clock.
Cheers.

Hi Rikki,
"Using clock out for the Gaia" is perhaps better described as "Using clock in for the Gaia from TP" vs using Gaia's clock.
When synced to TP's clock, your are using a superior SINGLE sealed oxco clock compared to the lesser Gaia's oxco clock. Using Gaia's clock means you do not sync to TP's clock and with both clocks in use that is expected to have higher jitters since they cannot be running in exact same timing.
Cheers.

Hi @RikkiPoo,
For those of us who have the TP, it's definitely wise to take advantage of the TP clock if its mated with their DDC, having said that, the clock in the Gaia is no slouch either, it is pretty darn good.
The clocking cables make a difference too and please scroll through to see where best to place your best BNC cable. I have found that footers make a big difference too. Do experiment. @Blake had posted some info regarding this as well.
