Mic Pres $1K to $1.5K

OK - I'll probably get blasted for this question, but here goes.
I have about $1500 I can invest in an all-around workhorse mic pre - a
mono 
unit - channel strip device.

I currently own a TC Gold Channel.

Mics are BLUE Dragonfly, Ball and KickBall
Violet Design Black Knight
SM 57 - Beta58

recording to Digi002

It would be used as a general purpose pre on everything from vocals to 
acoustic guitar to horns.
Please share your experience and recommendations.

thanks so much
Steve Hoover
