@Justasheep, our friend petmotel made great points. It is unfortunately true that the offer of mid-priced separates is quite depressing these days. Emotiva and Outlaw used to have pre/pro and amps that could be had for around $1k, but not anymore.
Buying used from a reputable vendor (or a trusted individual) is a great way to save money and get very good sounding equipment. Amps especially have not changed much over the years. New product hype apart, if an amp sounded good 3-4 years ago and was built well, it will still sound good today.
Preamp and processor, especially those for home theater, have become sort of "disposable" items, due to the continuous evolution of the digital standards (HDMI being the major "offender" there). Stereo preamps are somewhat immune to that, up to a point.
If you still prefer new and are okay with stereo only, perhaps something along the line of "out of the box thinking" could be interesting to you, like this stereo integrated amp from Outlaw:

The webpage does not say a lot, but if you click on "Manual" the pdf has a detailed description of all the features. With 2x110W on 8 Ohms and 2x165W on 4 Ohm over the full audio bandwidth and 0.05% distortion (real world power specs, for a change) it should be plenty of power for your rooms size.
