plinth shape in and of itself a dominant indication of presentation? never considered it before. OTOH a plinth plays a huge role in performance i agree.
certainly the Rockport, NVS and CS Port all have a big sound, the NVS and Rockport being more ultra dynamic in degrees, plus big and bold. unlimited really. but my room now is more supportive of that than when i had the Rockport......so hard to know exactly between those 2.
the Rockport has a 200 pound air suspended plinth made of a lead/steel carbon fibre encased sandwich. the NVS a cast aluminum skeleton. the CS Port and small square hunk of granite.
none large and square. but all very ’engineered’.
the Saskia idler is more focused and less expansive than these others, but that plays wonderfully to the forward lean to the bass, and tonal density that works for my favorite jazz pressings. is this related to the plinth shape? i tend to see the 180 pound slate Saskia plinth as adding heft and solidity, and the Pabst motor idler mechanical’s more scale related than the plinth.
