Jackman,
I can only compare these stands to the bar stools I was using before and you can imagine all areas have improved drastically. I could remove the beard to see if there is a difference in bass which right now is tight and full sounding. I suppose that would be the only way I could tell.
As far as the price, they're not cheap. They list for 560.00 but John gave me a pretty good deal.
When it comes to setup I have to deal with the current until we get our house. Any bit further out in the room will make for a less functional room overall, although I know the highs would surely open up more.
Oh and the floor, it's all good. It's been scruffed up for years in different areas well before we moved in. Right now I have pennies underneath the spikes.
