JohnnyMan,
Yeah, I had pretty much narrowed it down tot he mics you mentioned as well. It actually came down to the KSM44 and the Neumann. I liked the Neumann slightly better on my voice though. What I did do (at the Guitar Center that I was at) was record the 2 mics onto a Korg D1600 that they had there. I plugged in the mics, recorded two tracks of me singing, and then burned the wav files to a cd (that I just happened to have with me...)
I then took the CD home and listened to it on my stuff...in my studio.
It was still close (as far as the comparison was concerned). Listening to them at home was not that much different than listening to them at the store. I mean, it was "different"...but it didn't change my initial impressions.
The "kicker" for me was the price I got from Boynton on the Neumann. You can get KSM44's for around $550 all day long. So, I figured I'd pick one up later. Someday.
I did end up getting a used C414B-ULS on ebay shortly afterwards. They didn't have any of the AKG's at the Guitar Center when I went, so I never got to try one out. I bought it strictly on recommendation and reputation.
And, honestly, as much as I like my Neumann...I think my C414 is more flexible...
Boy...that's probably doesn't help you much, huh???
