Excellent !

Previous evaluations are not so good but perhaps I have a more recent version. My equipment: headphones Sennheiser HD800, cable XLR Sennheiser CH 800 S, DAC Sennheiser HDVD 800, Audioquest NG4, JitterBug, …, Bis electric plug… Music HD (HD Tracks, ProStudioMasters): AIFF, Flac, ALAC, 24->32 bits, 88->192 Hertz. My ears: 10 to 16,000 Hertz (you can them for example with Audiophile Hi-Res System Test - Great Sampling Tracks Included from HD Tracks). The sound is clear (no issues in every frequency cf.previous eval.), excellent harmonics, « presence » excellent (you feel like you’re just there…).
Enqueue is equal even better than iTunes with Bit-perfect plugin. I didn’t test others like Perfect. Enjoy music!
