I'm on leave today.
Alone and I got all day to fiddle with my rig.

For the fun of it.
Just now, I set the tonearm weight a wee bit away from the cart and adjusted the Anti Skate to almost near zero.

Wow. Everything seems to snap into picture (sound?)
Gone are the hardness and muffled top end.
The soundstage and timing did improve too.

I always thought that we need to dial in some anti skating control to counter the whatchamacall force the tonearm got itself into, but not in my case so it seems...
