My setup for 78 RPM audio restoration:
Technics SP-10R in Albert Porter panzerholz plinth
Primary arm:
Fidelity Research FR-66S direct-wired with Shure V15 Vx and dozens of custom Expert Stylus stylii with various truncated elliptical and conical geometries
The experimental arm/cartridge:
Dynavector DV505 with Soundsmith Strain Gauge cartridge and about a dozen custom stylii wth similar geometries. Just got the Strain Gauge and have been testing it...with a few easy tweaks, it can easily work for acoustical and early electrical recordings. You just have to invert the RIAA treble and add in the period curve. I use CEDAR Cambridge and can do it live but prefer to do it all in post via Scott Wurcer's hyper-accurate curves published in Linear Audio magazine. S/N ratio seems to be an improvement on the Shure, but still evaluating. Early signs are great--very similar frequency response to the Shure, and great transient response. Vinyl 78s are almost tape-like...groove tracing seems to be on another level. I'm going to temper my enthusiasm until a few audio engineer friends weigh in!
