I recommend the ARCAM FMJ line of pre/pros and amps. The pre/pro (AV-9) does not do video processing, only switching, but I assume that your source probably has a better processor than most pre/pros anyway. New AV-9s do have HDMI switching. I use component so cannot comment on the HDMI performance. I do know that they are highly regarded for music performance. When "direct" setting is selected, analog inputs are connected to outputs and all the digital circuitry powers down to minimize noise.
I have the P7 amplifier as well and am very happy.
