thanks for your answer, in fact, before to have my tascam, I utilize a small sony DAT, with which I could use a pair of KM with a PSP2 but TOO, a small binaural microphone I manufactured myself which utilize the preamp of the DAT. Now, I can't do that because the the line input of my tasccam don't have any preamp...
About the budget, not more $ 350 if possible!
in any case, It's friendly to answer me, there are so lot of question!!!
bye
