I have one of those too.
I have a few MXL mics.
None of them are as responsive as they should be.
You need some happening gain with your pre in order to drive them.
I like the CADs, APEX and ATs better, in that respect.
The MXLs are okay for instrument mics.
And they are okay on certain singer's voices.
As I said, you better have a decent pre-amp if you go with MXLs.
