Shure KSM44 vs Neumann TLM 103, TLM 49?

[rcook349]

I'm in the market for ~$1,000 mic for rock/acoustic roc vocals and also to be used on acoustic guitar (for same style).

I heard the Shure KSM44 and it sounded pretty good. But then I always hear to get a Neumann if at all possible because they're "the best" (although I've never heard one personally). Any idea how the TLM 103 compares to the KSM44 (they are both at thr $1,000 price mark).

But I'm also seeing that Neumann has just come out with a $1,500 mic, the TLM 49. Any comments on it?

Lastly, how much do you think I need to spend on a tube preamp to take advantage of these mics, $500 is what I'm thinking. Hopefully you won't tell me I need to spend too much more. Of course, the more the better in most cases. Regarding preamps in general, what brands do you like?

Thanks for any input,
Ron
