For anyone to have done a side by side comparison, who was not a reviewer like Terry London, you would have to put down just short of $6000 and then hope you got a working ProJect unit to make the comparison. In light of the multiple quality control issues reported with the RS2 why would anyone do that. After waiting for over four months for an ordered unit and being finally told by them and multiple other dealers that they had no idea when ProJect would deliver I gave up. Based on reports on the units that did show up at several dealers in the months that followed I'm glad I did cancel and move on. The Jay's unit is much better built and sounds great. The people who keep defending the ProJect unit bought early on when units were available initially and not after the demand went up and QC went down.
