Have seen such placebo effect for all new gadgets when they are newly launched - read a lot of really wonderful reviews in the past for iMod4, iMod5, Cowon D2, S9, J3, Colorfly C4, HM-801, 602, and of course the longest list for the Sony X1060.
Each DAP will have their supporter and no doubts they are all good players. However, all of us would want to feel good after spending so much for a gadget, and sometimes we are too engrossed with sharing all the positive experience that could seems biased.
To be fair to your wallet, take your time to do audition with all the DAP and buy the one that your ears love it, not the one that your eyes see it (i.e. not choosing one by reviews - they are not your ears).
I have bought and sold my HM-801 for 3 times (first one with PCM1704U chip not the U-K chip, second set and the current set with PCM1704U-K chip), all because after reading positive reviews of other DAP and then buy those. Wasted a lot of money and finally still come back to the HM-801, luckily before it is out of production.
Currently still nothing sounds better to my ears than 801. Not even the DX100.
Again, don't take my words for this. Go to try out a few DAP, best if you can do blind-test. Chances are you may just pick a iPod as best sounding (if your ears like it in the blind test) and save a lot of money!
Decided to give the DX100 one more chance and audition it again but this time brought my own FLAC favorites in a microSD card. Conclusion is still My HM-801 sounds better than dx100.
Those who have DX100 - enjoy your music man. Please audition the HM-801 if you all have the chance.
