I have a cheap 20 dollar radio shack dynamic microphone (lol). hooked up to an old technics deck which I use as like a pre amplifier. I know how sensitive condenser microphones are but for some reason my microphone still seems very very sensitive, and when I record if you just listen to the vocals you hear like a buzz noise in the background probably due to the cheapness, oldness of my equipment. but when you mix down you cant hear it at all really. well go here http://www.myspace.com/stevenforpresident and listen and tell me what you think of the quality. But yeah I have some money not alot but a few hundred so say if I bought like a 100 dollar condenser from ebay and a cheap new preamplier would it boost the quality of my recording substantially, also if you listen to my songs how far am I away from professional professional quality.
