UPDATE:
A/B'ing the TMA-1's against the M50's through two computers, TMA-1's are EQ'd as usual. M50's are at 25 hours burn in. (Let me know if I should expect much more change from 25 hours to 50.)
Sorry about the cr*p pics, using an old camera.
The TMA-1's are slightly darker, even with EQ'ing, but they do have the edge in bass. The bass is slightly punchier & deeper on the TMA-1's, compared to the M50's. The M50's have a slightly larger sound stage, and the bass hits almost as hard, they also have more speed for rock, metal, and other genres which ask for it. The M50's bass hits a bit more loosely compared to the TMA-1's, this is more noticeable in Club and Techno Genres, but it still has a good punch.
I recommend the M50's if you like faster genres like rock, and for thing's like classical as well. They are more balanced than the TMA-1's and sound less muffled than the TMA-1's in these areas. The bass, testing them both side-by-side, is slightly different. With a slight advantage in punch and extension going to the TMA-1's. It still sounds amazing with bass centered music, but simply not
as amazing as the TMA-1's.
I recommend the TMA-1's if you listen to more house, club, techno, and electronic music, because the bass and forward presentation make these sound like a dream. This is not to say they sound bad in other genres at all, they simply are not the
"best" in other genres, but in the ones mentioned above, they preform amazingly. Even in genres like rock, they make the kick drums,
kick drums.
