Hi, I am a classical singer studying in the University. I just bought MZ-NH700 Recorder, now I am looking for a very good QUALITY mic. mY friend haS been using sony ECM-MS907, She said it is very good. But she's a pianist, I am a singer.( Classical singers voice carry more and have more vibrations.) I used hers one time in a recital Hall, it didn't record my voice perfectly,(it got popping noise) especially on the high pitch. Maybe because I didn't know how to use it. 1)I also heard that AT822 is a good one, but the price is over $200. ECM-MS907 is $70-80. Does it mean that AT 822 is better? If there is no much difference, I would rather pay less for ECM-MS 907. Anyone can compare two of them? 2) Are there any other good mics that I don't know? I mean the quality is good as AT822, price is about the same. I can't afford if it's too expensive. 3)Oh, my friend gave me AT801 for free. I couldn't find it on the internet because it's the old model. I need to buy an adapter to fit into my HI-MD. But if AT801 can't record my voice as it is, I need to buy another one, it's unnecessary to pay $5 for it. Anyone can give me some suggestions on that? It's worth trying or not? Thanks so much for your help! Charlotte
