This setup has evolved over the years with virtually every part upgraded. The sound now is detailed and full and smooth, and great at low volume too. Vocals melt my heart with in the room realism and timbre.
I do add movable room treatment when necessary but find that the impact of what I have tried so far has been minimal. Examples of this include covering the table and absorption at the first reflection point (and more) on the left windows.
@glenmschneider I really don't know. I wanted the whole Sachs/Olsen suite. The pre amp remote allows for separate volume on each channel and with one of my ears hearing off that's great for me.
