I got pulled away to put my kid to sleep before I could finish my thought.
There is a interesting review of 3 of the top semi-affordable integrateds.

However, I would think any of these units would only work if you have the appropriate sized speaker for your room. In my room (same as yours) my KEF LS50's only work with room treatments, using the Peachtree NOVA 150. See photos. The Peachtree is very good for the price so I do not critique it too much

Another unit that would work with my KEF LS50 would be the SimAudio 390 Network player, but I would need an amp with that, but used cheap amps are easy to get.
