Guiy,
You should not have any problem running some of the better rated processors with you Simaudio Moon Titan Amp. I have not heard of any issues mixing and matching processors with amps.
I would always keep the video separate from the audio. If you look up Charles Hansen (Ayre) over at one of the other forums you will see that he highly recommends keeping them separate as the video is detrimental to the sound (specifically HDMI). Than being said I am not familiar with Krell processors other than they were not particularly reliable when they first came out. I used a Meridian 568.2 for about 8 years and it always performed with no issues. I would highly recommend using a Meridian processor. They are software based and easy to set up. You can get some good deals with their older equipment.
