How is the USB done and is the USB part isolated from the rest of the DAC? Can you PM me the prices? Thanks, Tony |

The USB makes use of a Cypress hi-speed interface which outputs paralell data. Then data is serialized internally into the fpga after a fixed clock. The usb isolation is appealing to some degree but right now means also bandwidth limiting, so we decided not to use it - and frankly I don't miss it in this design; the sound on usb input is just stunning.

This looks like something I've been after for a few years, a good way to find out if the pcm1704 is what people say it is!
How do we swap filters / update the software? I understand it is probably not easy to expose all this via USB to the PC but is there another way in? an interface for us to remotely update and swap filters (provided by you)? Thanks |

You can switch between 2 types for now - you can specify me the type of filter(s) wanted. Last edited by Lupulroz; 12th November 2012 at 05:11 PM. |
