A "pre" will not decode any of the digital formats you list. You mean a "pre/pro" or preamp/processor. The least expensive of these that will meet all your functional criteria are the Onkyo 886 or similar Integra 9.9. These are being replaced by newer, more expensive models right now.
Now, if you really mean a "pre" and will do all the decoding in the player(s) or source(s), then you might look at the Parasound P7.
Beyond those, there are many other options but you need to specify a budget for more info.
