...BTW, now you got me thinking about stupid tweaks that work. Here's a worthwhile freebie I discovered years ago and that Jonathan Scull, when he wrote for Stereophile, also made mention of...
When listening in the sweet spot, remove your eye glasses if you wear them. You'll be pleasantly surprised to find your music images a bit better. I bet some of you already have experience with this.
Oh...and definitely DO NOT hold a big board up in front of your head when listening to music. You'll most likely get bored very quickly.
sorry, couldn't resist that one.
Anyway, Cheers!
