Mapman, I'm not having any issues with my WiFi, I just wasn't sure - after reading what I mentioned above, whether or not I was "streaming" the full 24/48 sample rate. Evidently, from what I'm reading, I have in fact been receiving the full sample rate via WiFi. My music server does not sound bad at all; I just want to take advantage of any tweaks/mods that can take it to another level. I am running the Duet through a Cullen Stage IV PS Audio DL-III. I have the Channel Islands 9v external power supply replacing the Duet's stock wall wart. I would like to gain some additional transparency (a high end music server – if possible) thus, my search regarding mods & re-clocking.
