Your positive review and the other thread have me impressed with how powerful of a tool this is. I only wonder how it would fit into my system. I currently have all my processing in the head unit, and wonder how this unit handles sound post processing......With flat eq on input of course. A multichannel unit would probably be necessary, as I'm sure 4 two channel pieces would be cost prohibitive. Even then, can these units work together in multiples........maybe an 8 channel is down the road......
