Just out of curiosity, is there anyone here who has worked on a gold or platinum record who really knows what one sounds like before mastering?
Going a little off topic here, I know this indie artist who has sold tens of thousands of records, gets radio airplay with this record and even has a video for one of her songs, and she used an sm58 for her vocals... in her (untreated) closet.
I think the skill of the engineer (and of course the talent of the artist) has a lot to do with what results you will have, though choosing your mastering lab carefully is probably the most important step as far as finished product goes... as long as your mix doesn't completely suck that is.
Don't get me wrong, there are definitely 'bad' mics... and while the 990 isn't neccessarily on my list of 'good' mics, there are lots of good mics that don't cost thousands of dollars... what about 'Great' mics though? No such thing.
Of course, I've heard lots of people use this same kind of argument regarding price = quality when they will adamantly state that the only computer based recording system you can use to record a hit record is Pro Tools. After all, Pro Tools is the industry standard, just like ultra expensive Neumann, etc microphones. I wouldn't dare argue with someone who stands by that kind of logic.
My advice for someone trying to get something radio ready in a home recording setting: Get a mic that makes you sound like you, make your mix balanced (balance is the key) - and when your album is done and it comes time to press your first thousand, don't skimp on your mastering lab. This is really the step that will determine whether your final product sounds like an album or a demo. Open up one of your favorite albums that is more or less in the style of your own music and look at the credits to find out where where it was mastered, and try to send it to one of those places. You'll be glad you saved your money.
It's good to post audio clips like this though. Next time, I'd like to see some clips posted but without telling anyone what mics they are - and see which one people think sounds better before saying what they are.
