As as mentioned in earlier post, I will get the DAP if the price if attractive, and now, it is in my hand and listening to Eagle's Hotel California Live (1994)

. I DISABLED all the effects, EQ and sound enhancements, and with UM3X, one word...
AWESOME 
, but cannot overtake my D10 yet

The bass strong and punchy, mids/vocal and highs are clean, smooth and enough to satisfy my ears. Good match for Trance, J-Pop and anime songs. Need to listen more ... ...

The NC earphones vs UM3Xs? Mmmm.. no competition at all

.
The READ speed is around 4 MBytes/s, benchmarked with GNU/Linux's
hdparm.
BTW : My last Sony Walkwan was WM-DD9

Thank you.
