No offense inabsentia, but your thread responses are really quite silly.
You asked if upgrading mics is worth spending the money over $29 mics. Absolutely 100% of the people stated emphatically YES without a single dissenting opinion, then you debate them for two pages about why you don't seem to want to upgrade.
It seems as if you really wanted to ask this forum for confirmation that your recordings are good enough...but you are the only one that can answer that question for yourself.
You seem smart enough to realize that you're asking this question of a forum where some people have invested $10,000 in microphones. I don't make this statement to intimidate you, but simply to state, 'what would you expect the answer to be when it's intuitively obvious that the audience for your question are experienced tapers.'
They gave you what you precisely asked for, but you don't seem want to accept this advice. If that's the case, then why did you even ask?
