Star Sound Apprentice platforms

Try putting the amp and stand directly on the floor. The wooden dresser may be the culprit. 

i've had terrific results w/ the Apprentice 103 under digital. the key is the setup: the elegant and thoughtful design allows the user to orient the 3 points in such a manner that the weight of the component is equally distributed in a vertical manner---only when that is optimized will the platform work its best. ---no other footer on the market makes it as easy to find an ideal weight distribution of 3 points to the vertical plane. highly recommended. 

t_ramey, did you try the 103 or 104 under your monoblocks? I am revisiting isolation in my main system and have stacked another Symposium Svelte Plus shelf onto the existing Svelte but have found that some mass loading in form of granite slabs did add more authority to the music (I avoid to use weight description).  The amps are coupled with Symposium Big Footers. 
I may try Symposium  104 stands directly under the amps and no slabs.

they work like a charm.  Takes about a week to equilibrate.  That initial "thinness" goes away....

Sorry I didn't see this earlier. Yes I have the 103's under my monoblocks and they work great just like every other piece that I have put Star Sound platforms under. The amps are solid state but I've heard others say tubed equipment gets better results. My dac and preamp are tubed and they definitely have the more noticeable improvements vs my amps but I've had such good results from Star Sound that I don't feel the need to try anything else.

And yes to agears point, the longer they sit the better the sound.
