I’m always surprised by this arm. It’s a testament both to the quality and intelligence of the original Ortofon components, but also to Alfred Bokrand’s creativity, ear and skill. It is magical with an SPU, but i also found it quite good with a broad range of mm and mi cartridges that shouldn’t sound good in it, like a Pickering xsv-3000, and a B&O SP-12.
in the overly hyped and overpriced audio market we are in, the Bokrand is a star. Of the many arms i have (a problem, i’m a bit of a pack-rat for cool kit), it is surpassed in use onlty by the amazing Schroeder Reference, which has the benefit of an Allaerts MC-1b mounted on it. With the Bokrand, i have many options, and find working with various other headshells to find the right match very enjoyable.
i do wish that the Bokrand could have a simple VTA adjustment, like the Pete Riggle VTA for Rega from a number of years back, as that’s a bit of a crap shoot when i switch out carts as much as i do.
just picked up a Monster Genesis 2000 Sigma (ZYX, essentially) that i can’t wait to try in the Bokrand. I’m a sucker for older cartridges of any variety, ever since discovering Joseph Long and his restoration services.
Best of luck with the Koetsu. If it doesn’t work for you, let me know: I’m sure i have an arm it will work well in, and would gladly take it off your hands.
