Room treatment is necessary, and I know it equals the sum of its individual components. Acoustics are not as atrocious as they look. One side is open to the kitchen and the hallway. It's not the ideal room setup. But the upside is that there is no neighbor on that side of the house and no one in the back for 300 feet. With double-pain windows, I have no limit to how loud I want to play. The limiting factor is the eardrums.
@OP Thanks for the comment. Regarding acoustic treatment, alcoves can be problematic so that is probably a first starting point. After that, it will be first refection points on the sidewalls and the bass trapping in the rear corners. Gik are very helpful, so if you send them details of you room, they will make recommendations. Regarding software, you can do a lot with a set of test tones and an SPL meter. I would start there rather than diving into something more complicated. If you have room in your cabinet, the XP32 will sound better if the two amplification channels are not stacked with the PSU/Control box. The sonic character of the XP27 is very similar to the XP 32 - which is a very good thing.
Congratulations on your system - same amplification and phono stage as my own. Properly treating my room was the best investment I made in my system and was also the least expensive. You will not regret it - guaranteed.
