A series of perhaps ten separate experiments involving various combinations of the Micropoint Megafeet footers, amp position, large ebony triangles and the Ebony Interface Pucks footers with various configurations of fastened elements, some glued to and some screwed into the pucks, yielded the following summary observations:
-- moving the amp from its position on a 4" maple amp stand on Isoblocks on the floor up onto the bottom 4" maple shelf of my Samson rack significantly improved the sound
-- the best sound from all experiments was achieved with the following configuration:  an M3 size acorn nut was glued to the underside of the amp.  The nut's pointy tip, facing down, was resting on an Ebony puck with its three standard tiny brass washers resting on the rack shelf.
-- the big brass Mapleshade Micropoint Megafeet resting on pucks with the amp sitting on the Megafeet was close, but in my system the preceding setup was slightly better, although this is not a firm finding.  Also, the Megafeet take 3" of vertical space on the rack.
-- I also tried the Ebony pucks under my speaker spikes in place of the stock stainless steel "shoes", and the sound was a little better.
Other comments:
-- when using three acorn nuts glued to the bottom of the amp for purposes of resting on Ebony pucks, spacing the nuts should be as large a triangle as possible, with at least one nut close to the spot of greatest electronic activity on the amp base
-- acorn nuts should be as pointy as possible.  I could find none that were very pointy, but there are differences in pointiness among those I saw online.
-- the M3 size nuts were important, and were better than smaller ones (2-56) and larger ones (M5).
-- my system is a classic two channel system, streaming only, Vandersteen Model Seven MkII speakers, dCS Rossini DAC/CD player, and Aesthetix Atlas Eclipse stereo amp, all on a large, five-shelf Mapleshade Samson rack.
-- once the acorn nuts are glued to the amp, it requires some effort to position the pucks with the nuts resting accurately centered on them, although absolute accuracy is probably not important.
-- I used Krazy Glue instant glue.  Loctite also makes a good one.
-- these experiments were conducted compared to stock feet on a 4" maple stand.  Along the way I have also used Finite Elemente Ceraballs and Nordost Sort Cones (the middle model, brass?), the latter creating an obvious improvement.  I have not tried the uber expensive Stillpoints, or other of the many footer brands available.  
Overall none of this effected a jaw-dropping improvement.  However up in the airy regions where a lot of our systems reside, a small improvement is welcome.  The cost of the acorn nuts and Ebony pucks materials I've used and incorporated into my system are a bargain compared to the prices of many other footer systems.

These configurations did not sound quite as good as the baseline EBONY PUCKs with their ultra-thin brass washers.
