Your DL-III is an up-sampling DAC that will automatically up-sample your 16/44.1 files to either 24/96 or 24/192 depending on which setting you selected. In the case of CDs and 16/44.1 files, it is not necessary to convert them to higher bit and sample rates (which Rwwear refers to in his post). I'm not familiar with the M2Tech Hiface, are you sure it will support 192? Does MediaMonkey support 192? Many servers, such as Squeezecenter, are limited to 24/96.
