January 2022 update: the WallyScope is now available for shipping. The WallyScope makes the process discussed in this webinar far easier and more accurate than any USB microscope approach can provide.
On March 20th, 2021, audio industry reviewers Michael Fremer (Stereophile & Analog Planet) and Greg Weaver (Positive Feedback, Enjoy The Music, Soundstage and Stereo Review) and turntable designer Mark Döhmann of Döhmann Audio joined WAM Engineering to put on an instructional webinar on how to accurately measure your cartridge's Stylus Rake Angle (SRA) for optimal playback results.
In this webinar we discussed:
The ideal SRA we should set our stylus to
What type of stylus benefits the most from ideal SRA
WHY we need to align for an ideal SRA even though the recording industry does not have a single cutting angle for its lathe cutter heads
How to improve measurement accuracy with a basic USB microscope - even on asymmetric styli
How to decrease time needed fussing with the USB microscope
How to keep diagnostic equipment costs down, and...
HOW TO MEASURE DYNAMIC SRA!
The video, slide presentation and written instructions are all available below.
