I don't think it's a matter of being too technical. I love a good tech discussion, because hey, I'm in the tech industry. I think we understand the concept of not getting the stuff we're not using, i.e. not transmitting the high frequencies which a sub doesn't need. However, that argument is one of wastage, not one of performance/quality. What benedium and I are asking is, how does this translate to higher quality?
Latency was a performance benefit that was thrown about, but with aptX LL reaching sub 50ms latencies, are there additional advantages to proprietary protocols that transmit only sub 1KHz signals? How low are the latencies for these protocols?
Also, how about sound quality? What is the extra bandwidth that is freed up from not having to transmit high frequencies being used for? Higher bitrate? Higher sampling rate? More bit depth?
