You can’t do better than lossless audio transmission. The human ear can’t perceive higher than 20KHz. Uncompressed 32 bit audio sampled at 40Khz (double because of Nyquist frequency) is only about 160 kB/s. Even with 64 bit samples it would be about 320 kB/s. What am I missing here? Why can't a standard cheap ethernet cable be used for this?
