Tested against several high end DACs. This matched or exceeded each of them. Due to the filter options this DAC incorporates multiple final results from other manufacturers.
Added a DH Labs power cord. Slight improvement in bass definition. Once again, not certain of the cost benefit, but I am not inclined to go back.
Adding in a Silnote Orion M1 Reference XLR cable from the DAC to the pre-amp.
