which chip for portable DAC?

[powah]

I plan to build portable dac, but i have BIG question:

"Whih DAC will be optiomal for portable solution? Good sound quality and low power consumption?".

I found "Portable DAC"(www.headwize.com) but Andrija's project isn't good for me - it's too complicated & i can't find shop with EL2001 in my country. I need another solution so i plan to build my own "portable DAC".

Plan:
1. Torx 173 as "optic receiver";
2. dir1703 as S/PDIF receiver and decoder;
3. DAC - need suggestions...(PCM1710? TDA1543? ????)
4. Headamp - CuMoy HeadAmp with buffers, or smth like that,


Headamp will be powered by 1x9 battery(or 8.4 V NiCd accu).

I spent same days with "selection guides", "applications notes" etc. and still no idea.

thanx for ideas.
