More or less the same, Marty, on the Grado's and AT's.
Signet no longer exists - it was folded away into AT and never saw the light of day again. I think it was AT's higher end line back when.
Grado's track fairly poorly...and require a lot of optimizing to get right, but when you do, it's a wonderful device.
Don't know why Ortofon failure rate for stylus was that high.....they seem to have pretty good QA in Denmark
