Syntax, Great photo. But your SRA looks a bit off, based on Fremer's latest column in S'phile. 92 degrees, he says.
Not necessarily. Fremer defines the SRA as "the angle between the record surface and the vertical axis of the stylus's CONTACT AREA area..." He then goes on to say that "to properly set SRA you need to know the stylus profile contact patch of your catridge." If a cartridge has an "extreme-angle contact patch" (like the Ortofon A90), it would require that the shank of the stylus "be actually pitched far forward for the contact area's SRA to be at 92 [degrees]." He also warns against using the shank of the stylus as a reference for setting the SRA.
I believe the Delos has a line-contact stylus, just like my Soundsmith Aida, and the shank of the stylus might have to be "pitched" forward to get 92 degreees, like Fremer says. The angle of the shank of my cart's stylus looks very much like Syntax's Delos'.
I won't deny that I find it rather confusing and have no idea how to verify it is in fact 92 degrees at this point. It seems you have to use a microscope and software like Fremer did. Perhaps Mr. Carr can express his opinion on the subject.
