Hi Rebbi,
I've played around with different heights. I read somewhere that 26" if your room is carpeted, or 28" for different floors.
At 26", in my room, I felt the speakers were bright so I lowered them to 24" bringing the main woofer at ear level,and taming that brightness.
The Core Audio Designs stands are highly adjustable, 22" to 29", solidly made, and just beautiful to look at. Arnold Marr, the owner is a blast to talk to and he's very passionate about what it does.
Give him a call if you can, you won't be disappointed.
Keep me posted.
