I did manage not to screw-up the screwing-in of the spikes this time and the setup of the stands is now complete. Once again, thanks.
Two follow up questions:
1. I understand that filling the stands with sand or leadshot is sometimes done. Would I benefit from this?
I'm on the bottom level of my home with wooden floors on top of the concrete slab above the foundation. In other words, no hollow area below.
2. Before the stands, my seating position had my ears about halfway between the midrange and tweeter of the 802s, now with the stands, I am level with the "first" (of the two) woofer of the speaker.
Listening to the sound now is different, not unpleasant, but dare I say, slightly muddy in the climaxes of a thick orchestral work. I have moved my first-reflection panellings a bit higher and even (please don't snicker) placed two cushions under me to have me sit higher (it helped a bit). The speakers are in the exact position as before the stands and I am experimenting with placement, just haven't found "heaven" yet.
My first thoughts were that "I broke what wasn't broken" by getting the stands.
Any other suggestions or thoughts, from the Audiogon thinktank would be most appreciated once again.
