Elwood: Eyeglasses do change the sound considerably (not for the better, IMO). I always take mine off when doing other than casual listening. Think about it, you are creating two areas of reflection two or three inches from the ears (depending on how fat the head is) and they (the areas of reflection) are between the speakers and the ears. No kidding.
What s in front of your chair?
I'm condsidering putting an ottoman in front of my listening chair, but am concerned about sonic effects. However, could an ottoman be beneficial as a low frequency absorber? If so, what type of ottoman would be best? I'm thinking cloth covered with natural stuffing, i.e. wool or cotton. Has anyone experimented with this? I guess anything would be better than a glass table. I just don't want to buy something then not like it because once it's in, it will never leave(SO). Hey, maybe there's a product in this thread for some ingenious furniture maker: Audiophile Ottomans, $10,000, Chairs, $15,000.
