I've been using a Mk2 for several months now and like it a lot. Very open, airy presentation. Bass is great too.
What I didn't expect is how well Koetsus would like it. A 7g effective mass arm handling a Koetsu????
But both my retipped non-platinum Onyx and Blue Lace sound great on the Holbo, the latter a fair amount better, as one would expect. I've also run a Acutex 320 and Mutech Kanda on it briefly and both sound great.
In the same system I have a JVC TT-81 with FR-64S arm, and it does have a more meaty, juicy way w/the music. But is it better? I like them both a lot.
The set up is more tweaky than the JVC. Changing carts is a pain. And there' is a pile of white dust on the plinth where I end up with the CF brush. But I've got it covered with a cloth when not in use, so not an issue otherwise.
I've got it sited on a dining table next to the system and when the JVC was there, it would skip with footfalls. (Now it's on a wall shelf.) But thanks to the air bearing, I guess, the Holbo is not prone to skipping. unless I bump the table.
Overall, a nice addition to the system.
