Don't use the audigy? Man, some of these forums crack me up. Yes, I am new to this one, but not to others. Trying to find a home recording person that will say they use the audigy is like trying to find someone who would openly state they like Garth Brooks. No one you ever talked to liked him, but he would sell out auditoriums in 15 minutes.
Spin Doctors....that is how it all gets started. Pro-Gear companies spend a lot of money to get people thinking "If you are not using my product, it is inferior and will sound like crap".
I live here in Nashville, TN and can assure you that there are several "Home Studio's" and semi-pro studio's all over this city that use the SB Audigy 2 Platinum or the Audigy 4. If I get the chance, I will get some recordings and put up that uses the Audigy 2 and then you can be the judge for yourself. It all depends on the person in the computer hot seat on how well the Audigy 2 performs.
I make my living doing Vocal Demo's and am in and out of Pro Studios, Home Studio's and some that shouldn't even exist doing vocal demo's for song writers. There are more "Home Studio's" with the Audigy 2 than most people will ever confess, because if it doesn't sound cool to the general public, who in the hell will claim having one?
Buy what you can afford and and learn what you are doing. I learned a long time ago that people often blame the equipment for their lack of skill. The more money you spend, the less skill you have to have because the electronics themselves do most everything for you. The Audigy 2 will be sufficient to produce most any type of demo you would ever won't. It's not like anyone is trying to compete with the Major Labels here, is it? If so, I really don't think you should be on your home PC doing it.
