Largely agree with your findings on V2.00. I immediately noticed cleaner mids, better separation of instruments. Very welcome SQ improvement, and I was already satisfied with the 901 sound from V1.058. Now my issue is that every track is slightly truncated at the beginning, seems like the first 0.5 seconds of the track is cut off abruptly. Hopefully this will be resolved in the final version.
Also, I'm a bit surprised that there isn't a time display on the 901. I thought it would be basic enough to be implemented into the UI. Kinda sucks when I'm enjoying my music in bed at night and not know what the time is..l often end up losing a bit of sleep because I lose track of time, being totally absorbed into the melody (not sure if good or bad thing).
didn't think it was so important. Well, you know "SQ over convenience". My friends get surprised when learn the price of my gadget that doesn't even play video... well, not even display the time... :-)
