I demo`d a few DAPs today and also took along my trusty old Fostex hp_p1, I am happy to report it measured well (according to my humble ears) with the other DAPs -AK120, Hifiman 901, DX100, MS-AK100 and RWAK100.
You can read my bullet points here:
And Anakchan report (we went together, he just tried the DAPs):
I still use my Fostex and as time goes on I appreciate more and more what an amazing device it is, it pains me to use the iphone4 headphone out now days.
Just waiting for my Hifi-m8 to finally arrive then see which one I end up keeping!
