If I have to be honest I discover sra just recently. Before the only thing I knew was that the arm should be parallel to the record; so, two years ago when I fitted the cart I didn't check for sra. But from what I recall the stylus and the cantilever angle never changed through time. The cantilever though always seems to me to ride a bit too low, whit the tail of the cartridge almost touching the record. When I lower the stylus on the record the cantilever go a bit down, dunno if it's normal or if it should maintein his position.. any input from dv 20x2 owner would be very appreciated on this matter.
