i had it for about 2 weeks to try it out.....ive owned mostly sony atrac devices in the past, so was used to sonic stage crashing......yes, it took overnight to import approx 1500 songs, and many hours for me to convert and transfer into the HD-1......its a PITA, but as many say, once they are converted and in the player, its done.....
from my experiences (E5c's EX70's E3c's), the unit does not sound too bad.....i too noticed what i would call annoying static, but not as bad as Mavis's.....mostly with the highly sensitive Shure canalphones, but it was there.....exactly as if it were a cassette with dolby B on.....my biggest gripe was the low output volume.....firstly, the lineout feature was useless.....it caused severe distorsion...i had to use the regular phone-out to use in my car thru an fm modulator.....there was still more noticeable static in the unit than there was in my nw-ns70d flash player......sound can be good, and it can be great....depends on what earphones, and what the EQ is set on.....i did find myself constantly changing the EQ for various songs for the best sound......
another gripe was the display.....very hard to read without the backlight on, but with the backlight used, battery time is cut approx in half.....so count on MAYBE 15 hours with backlight being used often.....also, keep in mind that fast forwarding the unit (has moving parts) sucks battery BIG time.....when trying the unit out, i had both backlight on, volume high, and fast forwarded to many different parts of songs, and it killed the battery......
user interface was a little awkward, in that you could not search for a song in alphabetical order, you had to first find artist, then album, then song.....kind of a tedious process, but still works.....and yes, it takes a while to go from the a's to the q's if you have lots of songs etc......
i will add that i first purchased an ipod 40gig......i hated that thing.....huge, bulky, pain to change volume if you were already in another menu, sounded like crap to me too......tired my ears out very quickly.....very tinny with minimal bass......
the sony was an improvement considering the pretty good sound, but from a low output.....with the ex70's i had the volume almost at its highest setting to get best sound.....also, when calibrating the EQ, it worked best to start all frequencies at the bottom first, and go up from there rather than starting with the flat setting.....gets distorted up top......
i was hoping to wait for the hd3 to see if mp3 sounded better, but will wait for more reviews as others purchase it......
sorry for the long post
