It depends, mofat.
If you're just doing VO work then yeah, you probably have a problem with your room or something.
I have about 20-30 mics but I use different ones for different things.
I never really buy mics because they'll be better than the last. I just want them to be better suited to different applications.
When buying mics now I always try to aim at something that won't be replaced or upgraded.
For example, I won't buy an £80 pencil condenser. I'll just get the sm81s or oktavas or something.
I know there are better mics out there, but those ones are still commonplace in studios..
