In order to take advantage of the I2S ports on my Singer SU-6 and Gustard X-26 DAC (both recently acquired), I've been looking for a short and decent sounding HDMI cable that connects the IIS ports. Without a readily available one, I'm using a 1m SignalCable HDMI to break in the DAC. A 0.5 ft 4K HDMI cable proves too short. A 0.75m VIABLUE HDMI is coming tomorrow. A 0.3m (1 foot) WireWorld UltraVilolet HDMI is arriving a day after. I'm excited and expecting improved SQ when those short cables are here.
What I2S cable(s) are you using?
