Sorry, but I think that is an epic fail. Vastly better would be a track with piano, acoustic bass, drums with rim hits and cymbals, some trumpet or coronet, and a bit of female vocal—all recorded together in a real acoustic space. That’s the sort of track I use for many tests and for filter tuning. Far more revealing with transients (which are the easiest to focus on, and where the differences are heard between filters) than some soft plucked nylon strings. Let me know if you would like me to send you some tracks. I agree completely. I have argued for a couple decades that simple music doesn't enable the fine differences in codecs to be heard. I prefer massed a capella voices or multiple string instruments recorded to two mics or one stereo mic as the best samples to use for discernment. I think this is a major reason why symphonic music on CDs has been mostly disappointing compared to the same on tape or vinyl, and why chamber music blossomed on CD: less sound sources to expose clocking weakness and filter effects compared to good hi-rez digital or analog recording and playback. High-quality ADCs and avoidance of downsampling to 16/44 until the end of mastering has alleviated but not eliminated the problem, IMO. lmitche and look&listen 2 Mac Mini 2012 with 2.3 GHz i5 CPU and 16GB RAM running newest OS10.9x and Signalyst HQ Player software (occasionally JRMC), ethernet to Cisco SG100-08 GigE switch, ethernet to SOtM SMS100 Miniserver in audio room, sending via short 1/2 meter AQ Cinnamon USB to Oppo 105D, feeding balanced outputs to 2x Bel Canto S300 amps which vertically biamp ATC SCM20SL speakers, 2x Velodyne DD12+ subs.

All transducers are thoroughly and lovingly time aligned for the listening position. Link to comment
