Sound Anchor Stands...worth the money?

Instead of an anwser, I have a question. I understand that if one had wood floors or a suspended floor how Sound Anchors would benefit. Is my assumption correct in that if one had a concrete floor under thick pile carpeting or throw rug, that products such as Sound Anchors would really not benefit those situations? Like most I'm always looking for the next tweak to make an improvement.

How expencive are sound anchors?

After reading bulldogger's response im intrigued. It would be nice to have something custom made.

I have used both standard B&W 803 SA stands, and custom made SA stands for my Alon V's, in both cases a great product; adds mass and focus across entire frequency spectrum, and protects the bottom of your speakers from vacuums, etc. Great people to work with, especially on the custom stands.

If your stands have coupling points on the bottom, it really doesn't matter what they couple to, as long as it's mother earth. They'll go right through your carpet into the concrete. Don't have coupling points? Get 'em. peace, warren

I too can attest to the folks at Sound Anchor I bought a new couch for my dedicated theater room leaving my surrounds below the level of the back of the couch, after extensive research into wall mounts "argghh" I fortunately stumbled apon sound anchor called them up and with their help designed the exact stands that I wanted. They arrived in a timely fashion with a build quality that I had only dreamed of securely packaged and easy to assemble at 90 lbs a stand and 50 lbs of sand each they did the job perfectly. I never thought much of the sonics of my Thiel scs-3's until the sat on top of these stands now I understand the merits of surround sound audio previously I just did not get it but now I see. Sound anchors highly recommended
