The RR2150 can be used as a stereo preamp if the internal power isn't enough. Outlaw offers a Monoblock amp, the 2200 which is quite respectable and provides plenty of usable power. Outlaw is a small company and needs to concentrate its resources on what they do best. Each of their processors has the capability to operate in a stereo mode and they have plenty of amplifiers to fill any needs we can want. I don't see a big advantage to creating another line of equipment.
