If you hunt around, you can find an old pair of modules: Telefunken, calrecs, BFE, Filtek, Eckmiller...etc,etc usually not too expensive. and fer about 5 or 6 hundred you can get them racked witha PSU. Rediculously phat sound for a lot less than a new big name rack.
I really want to try the Chameleon labs strips...those are a lil over a stack for a pair, I believe...
