Hi Birdfan,
I wouldn't be too troubled concerning the combination of 16 gramms of arm-mass and the mass & compliance of the Sumiko Virtuoso, in the VE calculator a healthy 9 hz pops up. Well in the well-behaved area.
Your Sumiko is a mid-output MC, so, this so-called mistracking 'cos of excessive mass (tipwise), seems a tad too anxious.
I've run almost exclusively with HOMC's and they served me well when playing compressed recorded rock as with Killing Joke or well recorded 'all analogue' jazz as with Thelonious Monk. Mistracking has never been an issue. And some records have been with me for some 40 years (I started with a Denon 110) and , of course, show the occasional wear & ticks/plops. But have not been worn-out!
As of late I have a Soundsmith re-cantied real life Dynavector 10x4 with a sapphire/line-contact cantilever/stylus. And music sounds good. Have a go with SS operating on that cart. I bet it will come back with a vigor. A bit different perhaps, but def. NOT worse. Don't treat listening to ersatz thrills as conserved music as a religion.
Kind Regards, StefV.
