but if you use the coax input how is this dac then? i will not use the usb sense i have a HP touchscreen with coax out put built in. i love that PC. everything goes threw the touch. it is nice specially with my music. but back to the dac, do u think it is a good one if i use the coax or optical inputs? i will not use the upsampling. i really dont understand why this has a upsampling if the cs chip goes to 192 by itself. and is there mods to the new blueish boards? thanks mjc
