The new audio setup I ordered is arriving soon, so I figured I'd post a list of the new equipment I got.
Focusrite 2i2 Audio Interface
Wasn't exactly sure what exactly I needed out of an audio interface, but this one looked good. The preamps are apparently pretty great, and it got great reviews. It's actually arrived and I can confirm that it's really nice, and pretty affordable if you're getting into studio work. It also has 2 inputs, hence the name (2 input 2 output). I anticipate wanting to record more than one part at once in the future, so this just seemed like a logical choice.
MXL 770 mic
It's a fairly high-end cardoid mic, came with a nice shock mount, and recordings of it I've heard sounded great. It was on sale for $70, and sounds nicer than my previous ~$100 mic, so that's nice. Can't say much about it, because I haven't recorded anything with it. Will post demos of the setup once it comes in the mail. You can find these things on Amazon for fairly good prices if you have any interest in starting a home studio.
