All things are relative......
However, I don't think many here are going to regard MXL as high-end.
In addition, you may want to put down some reasoning as to why you are interested in these mics and what the uses will be.
I have not heard the mics you speak of.
I have heard a 990 and some green 87 looking MXL knock-off I forget the model.
I was not impressed by either.
They seemed to work well enough but, lacked and mojo or whatever it is that makes my ears pick up.
I have yet to find any LD condenser in the sub $500 dollar range that comes anywhere near an AT 4050. Sorry to be off topic.
Lastly, while audio gear is a hoorible investment...a 4050 will do you much better if you have to resell it. The MXL will not! buying quality tools as you can afford them is always cheaper in the long run. I chased the $200 U87
knock-off thing for years spending much more than the $1200 that got me a real one. And now I know why people are chasing this....... I should have saved that money and bought what I wanted in the first place. Let me take the hit on this one.
What do you want?
