I bought two of these mics, at an auction.
They were brand new...I immediately sold one on ebay.
I kept the other.
I used it on a couple of sessions with other people....
Then I tried it on myself.
I put it up against the C3 by studio projects, which is the mic for MY voice...
It was OK, no better , no worse, but the C3 is more flexible, and the shockmount is a hell of a lot cheaper.
If it didnt have the Neumann badge on it, and it was the same price as the C3, I would buy the C3, because the C3 is more flexible.
Given that the TLM103 is a helluva lot more, for MY voice, I wouldnt bother.
Now, mics I have been thru, trying to find the mic for my voice that I am happy with..... NT1, NT2, NTK, Rode Classic and Classic II,MXL V69G,
The C3 and C1, suited me better...but, thats just me.
Mics are good for some people and not for others.
If you are planning on recording lots of different singers, male , female, and non descript..8)...., and all you had to spend was the price of a TLM103, I would suggest, get a few lower priced mics...of different colors, different patterns, have some brushes to paint with.
But, if you are picking a mic for yourself, and the TLM103 fits the bill, just get it.
IF YOU FIND A MIC YOU LOVE ON YOUR VOICE, BUY IT!!
cheers
