I'm not familiar with the Pioneer PC-110/II, so I can't comment on that.
But I own a pair of 205C-IIL cartridges.
I think they are very good and probably would not trade them for any new moving magnet cartridge under about $250.
Jico makes three replacement needles and a couple others that are identical except for the color of the plastic.
.3x.7 elliptical on aluminum cantilever
SAS stylus on sapphire cantilever
SAS stylus on ruby cantilever
I have the first two and have no plans to buy the ruby cantilever model for $411.
The 205ED and 205EX Jico makes are identical except for plastic color.
Since the 205ED is $22 cheaper, that's the one I recommend.https://www.jico-stylus.com/product_inf ... cts_id=655
I think the EPS-205EX neoSAS/S is also worth the money at $211.https://www.jico-stylus.com/product_inf ... ts_id=1660
