I'm probably way out of line here but like that ever stopped me before..

. I think that telling someone that they CAN'T master something at home or that they don't have good enough equipment or that you can't do it unless you have $100,000 room or equipment, or you MUST send it to a PRO ME, is a grossly overassumed misconception.
Now I will state that it is probably correct a better percentage of the time, but just making a complete blanket statement like that is flat out wrong.
I would bet you that most of the ME's that are out there worked under some GREAT ME and they became great over time. But I would also be willing to bet that there were some, maybe a small percentage, but still SOME that for some reason, just could figure it out. Their ears just told them what to do. No special training or special equipment. They could just do it. I would refer to it as a God given ability.
So who's to say that someone here if not a bunch of those here are in the same category. Maybe the guy that wants to know how to master on his DAW was able to make some GREAT mixes without very little effort at all. Maybe when he is done, that CD will sound better than it ever would have if it went to a PRO ME.
I would be willing to say that every single one of us here that can hear and is patient enough and willing to put in the time and effort and won't stop until you know that you've done the best you can, could put out a CD that would rival anything out there today.
The statement was made earlier about it's ultimately going to be the listening public that buys the songs. I don't care one lick if a PRO ME or Engineer ripped my mixed to shreds and told me that it sucked so bad that it isn't worthy of a coaster; If the public likes it...then the PRO's can bite me.
I've been handing out samples of music that I've been recording to a bunch of people. Both musically oriented and not and so far, I haven't had a single complaint or bad review. Keep in mind that these folks, have handed it out to people I don't know either and have got the same results. Dont' want you thinking that the only person to listen to it is Mom...hehe..
So I say..go for it...if you give it your all and it still sounds like crap and you know there is absolutely nothing else you can do to help...then give it to a "Pro"....until then, keep cranking away on it.
God Bless!
