I have use my ART 9 on both the JVC 7045 and the Graham 2.2. I will at some point in the future, mount my Lustre GST-801 which is referred to as a heavy arm and give you an additional update using the ART 9.
Performs beautifully with the 2 arms mentioned. Reminds me of the
AT 180 ooc but slightly more refined. The ART 9 is a hell of a cartridge Fleib. I am tempted to get a ART 7 !
