Room treatment can be addictive

Alternatively, one might have a partner who is happy to devote a room to music and video. Kind of the ultimate in patience/indulgence/tolerance. She also told me to buy the car I had always dreamed of. Luckiest man in the world I am. 

We know who the boss is then.

Everyone loves their toys and should look after them…..Yes you are a lucky man

OP,

I'm lucky as well. While my partner gives me grief about my system... she is really supportive. She has seen me work for 70 - 80 hours for forty years and knows I earned my indulgences. 

What are the affects of first reflection from the side?  How does it affect the soundstage and vocal reproduction?

In my listening space, there is a large glass window to my left, and a 50in. LED TV to my right.  They would constitute first reflection from the sides.
