I think I've just found that link:
yep , thats the thread . It,s slightly ambiguous(sp) , and it,s a shame my interpretation wasn,t confirmed , but it seems to work .
Interesting, I have had almost the opposite experience; the focus and timing was improved dramatically when I filled my stands,
Are you using jmlab 905,s ?
The advice is specifically for that speaker .
It could well be just simply a matter of taste . I,ve found that I,m really sensitive to a bright treble (hurts my ears , as does distortion)
If your not using 905,s , then I can well understand . As standard practice , I have always filled my stands with the other speakers I,ve owned .
If you own 905,s , then it certainly seems to be becoming more popular over at ZG .
You can change the sound with attention to the speaker/floor interface but you cant change the sound of the room by doing so.
My room is boomy (like a public toilet

)
The main boom seemed to be in the alcoves (either side of the fireplace). so I have put shelves up .They,re homemade floating shelves , which means I have been able to make them different sizes and fill them , some with scrunched up newspaper and some with sand . Each shelf sounds different when you tap it .
The boom has been cured , whilst keeping quite a "live " room .
I was dreading putting my hifi into this place and I can honestly say that it,s the best sound I,ve heard from it .
Go figure
