i disagree on your theory that your ears can tell if you have jitter or not. all i can tell you is if you hook up the jitter device between the source component and the dac, you will hear a big improvement, something you won't hear until you hear hear the difference. just like going from a mid-fi system to a hi-fi system. you might think how can music sound any better than this mid-fi system. you won't know until you hear a system that produces music that you haven't heard before. also, i'm not talking about a shrill sound becoming warm or rough edges. a jitter device is not going to make a bad system great. my den system consists of a dk design integrated amp, dvp9000es, adcom gda-700 dac, totem speakers and subwoofer, and a connection from my music server. a decent system for a den. when i placed a cheap audio alchemy jitter device (get my feet wet with jitter devices), my sub was way out of adjustment (more powerful and way too loud), and the whole soundstage opened up. when you get a better jitter device, it opens up the sound even more. bottom line, i got as much improvement from the jitter device as i did placing the dac in the system.
