Yeah the Emotiva amps are good amps but there are always better options out there, Check out PS audio they have a pair of amps for $2100 and produce 700Watts @4ohms which is amazing. For the Pre/Pro I definitely would recommend Anthem AVM-70 the source output on those goes to 10V rms other than Marantz and Emotiva the max is 4.6V rms. The only down fall of the Anthems are not HDMI 2.1 except the AVM-90.
