Hi All, I just want to enumerate/share some problems met with audio play back: 1. MP gurgles/stutters with 24/192/HDMI - [24-192] Diana Krall - Wallflower (2014) - not listenable - HiBy does not - plays it flawlessly 2. SACD/DSD in MP is still shown on 176 KB - not sure if this is only representation or real conversion - HiBy shows the right info 3 . Nothing improved/changed in USB audio - MP still does not detect any of my 3 ext. DACs - HiBy does and plays 4. Switching to SPDIF - produces no sound Baseline - I use z1000 pro mainly as transport/source for music play/collections; Either through z1000 pro->denon 3600 HDMI or z1000 pro->ext. DAC(s)->Denon or Pioneer analog in. Please advise.
