I bought the Korg MR-1, now $235 on Amazon, and want to upgrade the mic. Intrigued by David Battino's article http://blogs.oreilly.com/digitalmedia/2007...aural-mics.html, I am tempted to buy the Sound Professionals TFB-2s, $97, but am also considering Core Sound's Low Cost Binaural mic, $75, see http://www.core-sound.com/lcmics/1.php , or Giant Squid Audio Lab's Omnidirectional Stereo mic $65, see http://www.giant-squid-audio-lab.com/gs/gs-stereo1.htm. I do see the advantage of the TFB-2 in eliminating handling and rustling noises caused by handling, touching and moving the mics. I want to record music concerts. Based on quality of sound, clarity, lack of boominess, etc., would you recommend one of the three for this purpose? Are there comparison clips on-line that you are aware of? Thanks for your expertise, Rob
