using hokey pucks for isolating speakers from the

What the puck?LOL..How about the difference in wood used?Say mertle vs. maple?

Take a look at Herbie's Big Fat Black Dots, down the page a bit here. I haven't tried them but they look promising and not too pricey. He has other sizes, also.

Three of Herbie's Big Fat Black Dots are supporting each of my tall and heavy speakers although four would avoid any chance of tipping if speakers were to be bumped into.
Clear, natural, and extended range performance by transmission line bass and ribbon tweeter design is the best ever with these modestly priced Dots. It's very well worth the slightly greater cost compared to hockey pucks
They are sold with 90 day return policy which should allow adequate time to hear for yourself if wonderful in your system.
