Schroeder arm and cartridge and simply move them from table to table. The arm is mounted on a "pod" that has no connection to the plinth so it can be "hotswapped" ala the Lab 47 arm. The Two plinths pictured are a solid maple one and one from delignit. Each plinth had its own character and more time is needed to get the "sounds" of each sorted out.
Speaking of the sound, the system we were listening to was also unique to say the least. It consisted of 3 pair of Quad ESL 57's arranged in an interesting manner. Two of the units were stacked and facing outward and a single unit was traditionally placed facing the listener. To make things even more interesting the three units per side were wired in series to net a 48 ohm load and were driven by vintage PP triode amps (Leak, Beam Echo, Marantz 9's and some sid smith 300B's).
