Telescope,
Reference 3A recommends using Blu Tak, at least with the Dulcets. I found that the "pea sized ball" recommended in the owner's manual was too much. The speakers ended up sitting about 1/4 inch above the stand's top plate! I called Reference 3A and asked Tash. He said that was way too much; you want the speaker coupled to the stand but sitting as close to the top plate as possible.
To remove the speakers, Tash recommended warming the Blu Tak up just a bit with a hair dryer set to "low," and then lifting them off the stands with a twisting motion. This worked fine, thank goodness! The finish (piano black) was undamaged.
Next time around, I took VERY small bits of blu tak and kind of smeared them out very flat onto the top plate of the stand in the 4 corners AND in the center (Tash emphasized this). Now they are coupled but nearly resting on the top plate.
Do they sound better this way? I THINK so... bass seems tighter, for example. But I wouldn't swear to it. I think you have to experiment.
