i read an article of neumann some time ago and i remember they mentioned that they invented the first transformerless 170 mic cause of the lower self noise and the resultion of a bigger dynamic range. The converse argument would be that an output transformator increas the self noise level and cause of that a smaller dynamic range... and as more i studied transformer here, yes transformers have their own sound character.
In fact, replacing a transformer with a electric ciruit saves space, money (to the manufacturer) and all these "character-aspects" coming with a transformer.
Rossy, I dont think theres not much more to discuss, not???perhaps i am wrong... but for my case transformer or electrical circuit (transformerless) are just two different sound influencing things which can not be discussed so much as every transformer sounds different. but generally transformers seems to be sensible parts that come with little self noise and increase the dynamic increase. The transfree circuit seems to be a low noise/low cost alternate which should must be more linear but must not sound better. For aspects you want to use a large membran mic for example nature/atmosphere recordings with low noise i would go for a tlm or a small membran like km184.
Perhaps it is not wrong to say that all tlm Mics aren´t noise sensible and have a really litle self noise floor. That is not mean that they sound "good" to me but for noise and dynamic aspects they are good. Talking only about output transformers or the transfree circuit should give the same answer, i think... The tlm 170 is a really good mic the tlm 103 is not as good sounding to me and so i cant speak tlms sound bad or good but both have no noise!

TLMs could be build smaller, cheaper... many people who are interested in a cheap low noise mic of neumann like the 103. Wait... the tlm49 is big... why is it big as it could have less reflection with a smaller body. The technic of a tlm49 is just as big as a coin. They just acquire more customers with this big case and the sound aspects are on second place... thats why i sould my four tlm49s. it is a case bluff. The sound was not my taste but interesting ... however, no noise

.
and "abbey road d enfer" was right, i cant compare tlm´s with my personal taste or other mics... thats nothing to do with the topic here.
But i dont think hes right with his mention that an output tranny would have no relationship between noise performance...
