[QUOTE="pwatts, post: 1069183, member: 146"] From an engineering perspective I absolutely love this DAC. I spend lots of time going over pictures of fancy digital gear, trying to figure out what makes them so special and where I would have done things differently. This thing is just so well executed in all ways. My only concern would be emissions radiating from the switching power supply module at the bottom, but I presume there already is some shielding in place (preferably not just aluminium). From what I can gather they use an FPGA for the processing and then individual CPLD's (small FPGA's in a nutshell) for driving the actual R2R section: this is a very wise step and exactly what I had found with FPGA-based class-D amps back in the day. Of course there are other areas that can benefit from improvement but that would raise the cost and size. Overall, especially given the price, this is just exceptional value for money for what you get in terms of hardware design - I deliberately don't mention anything of the actual software since it's a separate matter, and likewise the sound performance for the same reason.
