Given your stated primary interest in 2CH, suggest the Aragon Soundstage. Original list was $4k and have seen them in the classifieds for $1500-$2000. Will provide all you need for HT and the analog pre is essentially their well regarded Aurum. Can be upgraded to their latest, the Stage One later if you ever feel the need.
Has full analog pass-through, so your vinyl, SACD, and/or high quality external dac are not converted by the Soundstage's internal dacs. Many manufacturers don't provide this for some reason, which is a must for someone who's primary interest is stereo, IMHO. Not familiar with the pre-pros you've listed to know if they provide it.
With the money saved out of your budget by this approach you may be able to do some of the upgrades of other parts of your system that you want to accomplish.
