The TLM 170 is based on the U 89 capsule.
The TLM 127 is based on the TLM
103 capsule. I'm sure there are other differences.

I missed the first part of this thread but was just wondering, what are the
differences sonically speaking between the TLM103 and U87 ? Elsewhere in
this thread I believe it was said that the 103 capsule was related to the
U87 capsule. At the Neumann site it recommends the 103 for louder high
transient things like percussion etc, while the U87 seems to be recommended
for less harsh things such as piano, vocals, etc. Just wondering, if you
put a 103 and a U87 up on the same sound source, how they might compare
sonically? I think the 103 is a great mic, but there must be a reason why
the U87 costs considerably more and has such a huge reputation. The new
TLM127 seems to be a cool affordable good all-purpose mic, but as someone
else suggested, if you already have some 103s in your mic drawer, a 127
might be a bit redundant. - wg
