Have you treated your listening space?

Yes, see pictures of my room in system listing. Used Ready Acoustics panels, which I recommend.

Have not found the need to use very expensive treatments. by using area rugs and furnishings along with art work on the walls and floors seems to do the trick for me. I want good sound but realize I live with a family and can not have the room looking like a mad scientist lair.

I'll bite.
Having a dedicated music room that's fully treated has given my sound stage a true 3d image. I will state that before I put the treatments up and lazer aimed everything, the imaging and clairity was lacking.
I only thought I had a great system before.
You can't buy equipment that will come close to what treatments will do.

I am a big on just using the stuff one has in the room, naturally, to adjust the rooms acoustics.

I use floor to ceiling bookshelves filled with DVDs, and common drapes, and normal furnishings to alter the room corners..

Wierd stuff just makes it clear you are crazy. (as an audiophile the stuff makes perfect sense. To anyone else it is all psychotic madness you filled your home with)
So pick your poison carefully. Especially if you are single and wish to attract a mate at some point.
