http://www.macworld.com/article/52765/2006/09/usbmicrophones.html I have been reading forums and reviews like this and the conclusion for USB mics is generally "not very good", I was wondering why these mics under perform compared with regular XLR with a preamp connected to PC. I am a noob starting to record and have a few questions, if you can please number your answers so I can understand 1) what part of the XLR mic to PC set up determines the mic quality the most? (Is it preamp/interface?, if so... next question would be..) 2) is it that these all-in-one USB mic have bad preamp in them that they underperform? 3) is it true that for a single USB mic it might sound like a good deal because you are spending less money, but if you want to add more mics in the future, it actually gets more expensive because you have to purchase anothe USB mic which includes the cost of the (crappy) preamp etc again.? 4) if I actually spend more money purchase a good interface, will a normal XLR mic outperform a good USB mic such as, Samson G-track, Blue Yeti etc? 5) please give a package of normal XLR mic components that outperforms G-Track or Yeti. Thank you!!
