Hello jjss49,
Although there are a couple of long running threads about the Art9 here on the gon, some info below:
Break in around the 100hr mark, gradual improvements will occur in the meantime, and full performance will be around 250 hrs.
VTF; I run mine at 1.75g, after much experimentation. (1.55 - 2.0g)
This is in SAEC 506/30 (12") arm with the SAEC ULS 3 AL Oxide headshell. A lower mass arm may work better at slightly increased VTF.
VTA; I use a 10x magnifying glass and study the stylus as the record is spinning on the outer grooves, very slight tilt forward is where I have settled over the last year with the Art9. IE, tonearm slightly UP at the rear/pivot.
Load at 100ohms, but do experiment here. My own tonearm/internal wiring gives 72pf of capacitance which is ok, so the 100 ohm setting on the Concert Fidelity SPA-4c is best. Other phono stages may differ here!
One thing; as with all cart's is to keep the stylus truly clean and clear, again with a mag glass. This is imperative as you probably know already..
Have fun and let us know how you find the ART9 over time against the Koetsu Black too..
Best, Paul.
