I like the Placette buffered preamp - has none of the hard grain of most moderately priced ss preamps, and has the pacing that is so hard to find in valve preamps. Can be had on a money back trial - but its construction is tenuous. My advice is don't open it and you will never know. The E-A-R feet will only handle about 10 to 20 lbs comfortably each. Six or eight of them ought to be right for the SA102. The Walkers are very good, but with less warmth that the E-A-R feet. In fact the E-A-R are just a finishing touch - the key issue is those Neuance shelves (or something similar) - I have not tried Ken's new version for heavier components.
By the way JD - are you using the SA102s bridged, or bi-amping? There are downsides to using Plinius amps in balanced or bridged modes.
