I'm on the look for a DAP that has at least 32Gb internal storage, (preferably more) or the option to use a mini SD-cards, is robust and small enough to be in my pocket all the time, has fm-radio, gets at the least ~12 hours of playtime without charge, has Spotify offline playlist capacity and either has great sound quality straight out the hp-out, or possibility to use line-out or external dac. Headphones I will mostly be using are Sony MDR-EX600 and possibly Koss Pro DJ100 or 200's once I'm able to get them. At work I would use cheaper iem's listening for casual radio etc. straight out the hp-out, so sound quality in that use isn't the biggest priority. The amp or dac would be bought later to best compliment the device I end up choosing, but would be something along the lines of Fiio E11 or comparable for just the amp, or Fiio E17 Alpen or Leckerton Audio uHA4 for the dac. Portability is an important factor even with the amp/dac.
I'm pretty much decided on the N8, since there doesn't seem to be many options, Galaxy PMP and the new Sony Z are too big with their 4+ inch screens, Philips' Gogear Android player hasn't got enough storage space. ITouch is pretty much the only other viable option, what it lacks in sturdyness and (cheap) storage space, it makes up with the amount of accessories. But I don't feel it's worth twice as much as the N8, new or used, especially considering that with the N8 you get apparently a very good camera and some other minor things like the fm-transmitter and aluminium shell. This usb out would be just icing on the cake.
So what I'm asking, is there something that I haven't considered in this reasoning, and should I just cough up the cash for iTouch, or is the N8 a viable option for it?
Also, has anyone tried if the usb out works with the Leckerton uHA4? And what's the cable situation like, is it possible to get an IC that makes it possible to put the N8 and dac in our pocket, probably a micro to micro with 90-degree left or right plugs would be required. There was an ebay link earlier in the thread about custom usb-cables, but it was dead.
Thanks in advance if someone can shed a light on this.
