The TLM107 is my first Neumann mic and I did a lot of research, before buying it.
It is very neutral with clarity and detail at all frequencies.
Great at vocals, acoustic guitars, percussion, strings and just about everything, I've tried it on!
I like it better than my AKG C414 BXLII, which is also a great mic, but a little too bright in the "s" frequencies and in some cases a little "boxy".
The built quality is very high, as expected from Neumann.
I suggest that one should also buy the dedicated shock mount, as it is sensitive to handling noise, more so than the AKG C414.
The only thing that I don't like so much, is that the controls are on the back and they go off in 15sec, so it is a little difficult to change settings, if you're recording yourself.
Otherwise it is my best mic so far!
I guess only time will tell about its durability(especially in the electronics department)...
