Sorry, I was going from memory on the model number. Yeah, it's Sony's top of the line one point mic. The cheaper ones I've never tried, so I have no clue, except they'll do something. I got mine on ebay for $150, but I had to look around for a while. You know I'm there for you. Pandora tech is a fairly strong suit with me. I've actually used it as an outboard reverb unit in a pich. It's really not bad. The little thing surprises me every day. I'll tell you this, though. If you wind up with an ECM-MS957, once you figure out how to get from a stereo miniplug to 2 XLR males (that's a fun game), you'll find the mic has a wide variety of studio and remote applications that add to it's functionality. Patched to my Avalon, it is an impressive acoustic guitar mic. It has 90 and 120 degree settings, so you can adjust the hard wired stereo separation a bit. The mic, it's folding desk stand, and cable fit very well in the zippered case for an Oktava MK319.
Remember this, though. You're the one that says you should invest in good mics that will last and get the job done. I'm here to tell you that the little Sony and the Pandora *love* each other. If it doesn't have to be hyper-portable, just use a DMP-3 and whatever mics you like.-Richie
P.S. The guy who does the sound at Jamfest (Me old guy-memory not working on his name) has an AT stereo mic that he uses with a PDA based micro recording system. I don't know the model number. We plugged it into the Pandora for a couple of minutes. Through Sennheiser HD280's, from what I can get just from ambient noise/background music, it sounded "adequate", you know, plain vanilla usable.
The ECM-MS957 (I'm presuming electret condenser mic, mid-side 957) has scary but tame-able, highs, kind of like the KM184. With a little judicious EQ, the Sony mic rocks.-Richie
