I have a pair of outlaw 200 watt mono. Blocks , i think there is a large market for high quality 2 channel gear,i am aware recievers ability to be used as a pre amp,that would lead me to think it would be very easy to use just half of the reciever to buid a 2 channel pre amp,its already been designed, i say build a 2 channel preamp to acompany the 200 watt mono blocks and see how they sell ,there is a large market out there .
