Ha ha. Yeah my main mike at the moment is an NT2. In comparison to my Shure SM58 it sucks in alot of detail. I really like the 58 as it's really east to use. You tend to get a big chunky sound that doesn't require much tweaking from the desk. The NT2 breathes higher resolution and realism into the sound. Highly recommended.
Any article I've read on mics indicates that you need a good quality mic preamp to really get the benefit. A high quality desk will have a whole pile of these built in at wonderfully high cost. However, if you, like me, tend to need to record only one track at a time then it makes sense to record using a high quality channel strip. A one channel mixing desk in effect. I use a Focusrite platinum voice channel optimised for . . .well . . .voice I suppose. This incorporates amplification, noise reduction, saturation (kind of valve type thickening), compression, EQ, and de-esser. Basically it helps rip the musical information of yer mike and then gives you plenty of scope for some creative polishing. If used subtley it can make your recordings sound a little more "professional". Well recommended.
However, with the advent of digital stuff some of the good quality analogue gear has dropped in price so keep an eye open in the ads.
