I used to have that same preamp and with your budget you could certainly improve on it. Browsing the listings a few things that jumped out at me.

If you can accommodate three chassis this is a serious dual mono preamp and a really great deal for $3495.

I have not heard any of his gear but Nick Doshi is certainly getting tons of great reviews and show mentions and this preamp looks like a nice deal.
And of course you could always upgrade to a new Herron.......
