After searching forever for a very portable solid state digital recorder that could record stereo at CD quality, it seems that there are now(at last!) two viable choices - The Edirol and Marantz 660. The xlr inputs on the 660 are obviously preferable to the mini jack but I need a recorder that will allow for good recordings of rehearsals and performances on the fly, sometimes without a external mic. Any thoughts/experiences about the internal mic situation on either of these machines? Have any of you played with the 660 yet?
