I use DeHavilland Ultraverve preamp with my 4BSST and an old 4B running two zones. Minimalist design so no balanced. I sent it back and Kara rigged up a custom mono switch. Very happy with the sound.
I have also used Bryston BP 20 and Van Alstine T8 both of where very satisfactory. The Bryston BP has mono and phase invert both of which came in handy. From my experience you cant go wrong with any of those choices and all are in your range.
One day I want to try Audio Research and Mc preamps too.
