Isolation stands for basements

First time poster, long time reader.

Just wondering if isolation matters in a basement on a concert floor. I just have a cheap Wal-mart stand right now, but am looking to upgrade... and I'm not sure if it matters that much. I have OK stuff(Sim Audio 5.3 amp, Musical Fidelity A5 CDP, Paradigm Ref 60 speakers) so I'm OK spending about a grand or so on a stand.

Any help would be great.
Yes,It does. Get as good as you can afford. you don't believe the difference it can make.
Sand filled Skylan stands work very well on concrete..I use the Herbies Fat Dots between stand and Monitor with great results......
