What do you sit on?

I sit on my fat a$$ per the wife. 
And it is on an IMG recliner and ottoman. 

My friend had a dedicated listening room designed in his newly built house with dedicated circuits and lots of RPG room treatment. His system was comprised of very highend equipment like Mark Levinson, Krell and Wilson Audio.  Our group of four assembled one evening to do some serious listening, After a few minutes, we all agreed that his usually superb-sounding system sounded terrible. The only thing that had been changed since our last listening session was the addition of a new leather sofa that his wife admired.  We picked it up and moved it out of the room.  Instantly, the room sounded as good as before.  We moved it back and the system sounded awful again.  Needless to say, we moved it out one more time --- and it remained out !  We never figured out why it made such a drastic difference, but it most certainly did.
Make sure you can return any new furniture addition to your listening space.

My arse.

Since my little Maggies, as set up, image incredibly well, in or out of the sweet spot and being line source, seating height isn't critical, I am most happy with my three cushion Flex Steel sofa. It is medium firm and comfortable for long listening secessions. I usually sit in the center cushion, but if company is over or wife joins in on the session, the  cushions on either side make a comfortable and good listening seat as well. As I do a lot of late night listening, it's nice to stretch out and relax for a bit, when I get tired of setting and still be able to enjoy the large full scope of the performance, without everything being sucked into a box...Jim
