I have 2 systems in one. My 2 channel preamp has cinima pass through. I listen to mostly vinyl and is why I went this way. I am thinking of seperating the 2 system because of grounding issues though. If I did not listen to vinyl then I would have only 1 system and it wound be the HT system I have now. It sounds great for 2 channel digital sources. If you are going to a ht processor make sure you can update it with software. HT system change much more often than 2 channel. If you cannot upgrade it then you will be replacing it in a year or so.
