Hi, So my question is basically the thread title. I know there are DAPs with the ability to have 2 micro sd cards but I don't know what their sound is like compared to Cowon, with whom I've been with since my iAudio 7 when it 1st came out or somewhere around then. So if anyone knows of a technology or a way to do this then I would appreciate some help. If not, can someone tell me of a good battery life like the PD or something close to this, sound wise and the ability to take 2 sd cards and around a similar price like the PD please? Thanks in advance!
