So, here is what I did and how the sound changed:
1) updated my W7 HP to SP1 with few updates after SP1 according to findings in this thread
2) upgraded HiFace MK2 drivers (started to use Young's driver instead of Hiface's as several people have conformed as sounding better)
3) installed the very latest XX (before was couple minors back)
Bottom-up:
Bass: improvement incredible. Depth more, clarity and power. Now when I turn up volume, bass gets stronger and goes more into floor them comes up under me in my couch. Before, it was dirty and cloudy.
Middle: not so steril as before. Seems like a bit more mud in there, however resolution still high. Have listened 2 albums so far, but I guess must get used to that.
Highs: Not so sharp as before. Still crystalline and mild, but less sparkling. I need to get to used to that.
Overall sound picture has moved down. It is more kind of attenuated I'd say. At higher volumes it is perfect as sound does not attack you, it rather fills the space.
Afterall, very good indeed!!!! Thank you Peter for your work and do not pay attention to my topic with JPlay, just wanted to share the new finding and my experiment with both players. (Haven't bought the other one
)
