Essentially yes, but I'm not an expert. Always thought of it as some sort of a buffering mechanism, but I must study more.
Thought this one had an impact in one setup which I tried it: http://www.firestone-audio.eu/shop/products/allproductslisted/bravo.php
If nothing else, at least 24/96 is a plus to some.
That one looks very similiar to the Teralink X2 I linked earlier.
It feels good to seperate components, but I'm a bit unsure of using more than 1 clock, and any form of buffering (latency), I guess when listening to music latency is ok, but with anything involving a microphone, instrument, or audiovisual (like watching sports or playing games), then latency/lag can become very annoying, even if it's only a 50th of a second. For the most part ASIO can fix it.
