Who is using I2S cables?

I've been reading / watching info and trying to learn about I2S. Several manufacturers offer I2S connections (Topping, Pro-Ject, Jay's, Denafrips, Singxer, Raspberry Pi?...). I2S has been used internally for years (mainly internal CD to DAC connections) but some components have I2S connections. So, I'm confused and curious. 

1. Are you using I2S cables? What has been your experience? 
2. What components are you using I2S to connect?
3. Are you using an HDMI cable or so-called bonafide I2S?
4. Where did you purchase your I2S cable(s)?


@marco1 - yes, I agree. I am currently using the Gaia with AES3 which works well, but I think an Iris connected over i2s could still be an improvement. 

I am playing around with a DSP active crossover (dspNexus by Danville Signal) which would replace my T+, so I'm not going to invest in another DDC until I decide which direction I'm going to go. 

@jaytor. Interesting I remember hearing about this product a year or two ago.  Is it available now?  Do you have one?

@marco1 - It is available, but it is not in full production yet. They are still working on the software and an upgraded DSP module. 

I do have one and have been playing around with it for the past few weeks. I haven't had a lot of time to spend on it yet so I haven't gotten very far. In addition to my work, I have a couple other DIY audio projects that are taking up some of my time. 

I'm planning to attend the Capital Audio Fest in a few weeks. Al Clark (the head guy at Danville and HW designer) and Richard Hollis (who has done a few active crossover implementations with this unit) will be there and I'm looking forward to discussing the dspNexus with them. 

Very interesting.  I'll be at CAF too and will plan to check in with them.

Hollis Audio Labs is doing some very impressive stuff, they are using my amps in their setup at CAF2023, and I am looking forward to meeting Rich.
