I bought a Stax system (SRM-313 + SR-404) from J-pak.
He was always very friendly to deal with, and answered my millions of questions without getting impatient. He happened to be coming to the Boston area, and generously agreed to do the exchange right in front of my dorm.
The system came in great condition as described, and his soldering job (to reconfigure the 100V SRM-313 to 117V) looks nice and clean. I would not hesitate to deal with him again.
