I actually have this receiver and it sounds awesome. Sony first developed the S-Master for this 4.5k Top-of-the-Line technology in the early 2000's and then scaled it down for X walkman several years back. The F886 should be the third iterations of the S-master portable module.

I still cannot exclude high aoutput-Z, but it should not be because of that Tegra 2.
Yup, I'm in agreement with this. Love the sound of my S-master pro amplifier.
