I just bought 2 different styles of 0.1m HDMI cables to see how they compare to the 0.5m Emotiva HDMI cable. They are generic brand so the wire is probably lower tier but if length is a significant factor this is about as short as you can get them. Will let you guys know what I hear. The downside is that since they were so cheap, I didn't pay for expedited shipping so one of the sets won't be here for a month.
Does your setup support a 0.1M connection?
That's incredible. I had a 0.5FT cable at some point (now T Bone owns it), but it required my Singxer SU-1 to sit right on top of the HDMI input on the Spring. Now the shortest I can go is 0.5M, but luckily no sound difference I can tell of so far.
I wouldn't recommend conventional HDMI cable designs as it suffers more from bandwidth limitations, jitter, signal attenuation, crosstalk, and external EMI. A flat design cable would be best. This is why WireWorld is so popular. However, for a length shorter than 1M, the improvements in cable design might not even be audible to some people (or some setups).
I've had:
Sewell Silverback S6 0.5FT
WireWorld Silver Starlight 7 0.5M
WireWorld Starlight 7 0.5M
WireWorld Ultraviolet 0.3M
Monoprice Commercial 1FT
Kordz LUX & EVX
I sold the cheaper cables for peace of mind and ended up having only the Ultraviolet & Starlight. I did a comparison between the two and found them to perform very similar in i2S transmission.
Funny thing was, I wanted to save money and stick with the Ultraviolet cable. I figured silver plating will help with electron flow and keep the cable lasting longer. The Ultraviolet I had at the time was only 0.3M in length, but I needed 0.5M. The more expensive options I had was 0.5M, but it didn't give me any improvements so I felt it wasn't smart to keep them.
Right before buying a Ultraviolet in 0.5M, i noticed a brand that had a similar flat design, PE insulation, silver plated wires, and double shielding. It was called the
Apollo AV Lightning V2. For $15 I took a lunge and now I can happily say I'm keeping this cable. It performs on the same level of every cable I own, even the $250 Kord LUX reference! Probably the best bang for the buck cable I've ever bought.
I highly recommend it.

Can be had for cheaper on Amazon & eBay.
I asked Dave over at Apollo AV for a cross section of the cable's internal design to see if it's configured well for i2S and was pleasantly surprised. He cut one in half and showed it to me. Now that's great customer service! The core DATA, WCLK, SCLK, and MCLK signals are all well separated from another. The dirty signals (power) is isolated and shielded. No wonder it performs so well.
Just trying to save everyone some money.
