I have been using the B ULS a lot on certain "types" of vocalist, and on them, it is THE mic to use! Overall, it still isn't such a bad mic.
I found this. Via a solid state preamp, it tends to sound very bright. Via a Drawmer 1960 pre/comp combo, it sounds very silky and smooth.
I never liked the sound of the TL II for some reason, but it has been a few years since I used one, and really can't remember why. I do know that the BULS work very well in a number of applications, and again, is sometimes JUST the right vocal mic.
If this sheds any insight on this subject, cool. If you auditioned a good cross section of mics, and found that the 414 complimented your voice well, then by all mean, BUY THAT MIC!!! So many people around here DON'T compare mics on THEIR voice, and purchase mostly off of what others say about it, or what they have heard others do with it, and end up with a mic that DOESN'T compliment how they will use it very well. For LD's at the studio, I have a pair of vintage U87's, a 4033, a 4050, a 414 BULS, and a ADK TC 51. I can usually count on one of them to provide just what I am looking for in a situation where I need a LD. But, I could never choose JUST ONE of them. I like having the variety. If you need "just one", you should NEVER purchase until you have tried a bunch to see which will best compliments what you will use it for. Don't take what others say about a mic as the best thing for you, because other people might expect a very different sound, or have very different sounds they are tracking that their "favorite" sounds good on. The reason most big studios offer a variety of mics is because they KNOW that no one mic will work well for every application, and that not having the variety means the sound sought will not be possible. Since most of you only need to record yourselves, you should take GREAT CARE in selecting the right mic for you. You cannot make that choice UNTIL you have tried a bunch out.
I would compare purchasing a mic unheard to marrying a woman you have only read about.
