I'm currently deciding on either buying a RE-20, SM7,AE2500, or a D6. I've used every mic (and some I left out such as a D112 which I hate the sound of) I listed except for the AE2500 which is a new mic AT made which is a dynamic and a condenser mic housed in one body as a daul element kick drum mic. Has anyone used this mic yet and what was your response.
