Transparent Digital Cables - good for any level?

I noticed that Transparent interconnects and speaker cable can cost ten of $1000's, but their most expensive USB and HDMI cables cost about $300 and are indicated to work with any "level of musicality" in their ranking system. I need a good HDMI cable for I2S and it would be great if I only have to spend $300 to get world-class performance. Anyone have an opinion on their USB or HDMI cables?
