I love the sensuality and mind-body connectedness of these early instrumental compositions by the likes of Josquin Des Prés, John Dunstable, and my favorite composer of all time, Anonymous. Using the HoloAudio May DAC, I streamed this recording through both the old and new Sphinx. The original Sphinx played these songs enjoyably but with an almost imperceptible slipping-clutch effect: Some of the bite of the flute's top octave disappeared, and the midrange blurred just slightly. In contrast, the improved Sphinx V3 is equipped with a no-slip competition clutch: It delivered a good amount of leading-edge bite and trailing-edge flow. Bass felt quicker and more articulate.
