Well in reality the TLM103 isnt as useful as the TLM102...time will tell us more...but from what Ive seen so far the 102 is being used on most everything in the studio...while the 103 was more of just a vocal mic.
Its a good thing since they can also be mounted in spots that many mics would get in the way when doing...Neumann mics are nice...the last thing you want are dents from drumsticks.
