"Budget" preamp choices.

All right, so here it is: I need a new preamp, preferably $750 or under. The rest of my system is as follows: Rega Saturn - Pass Aleph 3 - AKG K1000. Soundstage, beautiful mids, and detail are my biggest things. I've been considering getting the Rega Cursa, either 2000 or the recent '3' edition, to match my new CD player, but I'm open to all kinds of suggestions. The only restriction other than price are it can't be too tall, as my top-loading CD player already has the top space in my rig. I generally prefer solid state, but if you guys think tubes will add just the right ingredient to complete my rig, recommend away!
