I used Stillpoints under my Crescendos but removed them after a few months because they thinned out my midbass; Audio Points were very good but you may want to look into a newer isolation device called IsoAcoustic, Gaia.
I might try the ultra5s as i might have access to them later on. I've noticed on the net that different speakers weren't so good on the ultra ss but came good with the 5sThe Gaias appear to be just sobothane, i might be wrong
