Sidebar 3: Measurements I measured the DirectStream MK2 first using my Audio Precision SYS2722 system, then with the magazine's higher-performance APx500. The review sample was fitted with the v2.3.5 FPGA firmware, but after I experienced some anomalous measured results, I installed the v2.3.3...

Thanks for posting that. We an infer SINAD easily from that graph: The third harmonic is at -68 dB. So that easily sets SINAD's base case value at that (noise and other harmonics would derate it more). The previous version actually had lower distortion: The highest peak was second...
