Alex,
I have built several Lencos with the RB300 and Denon cart. This is a very good synergistic match. Personally, I see no need for tweaks. But, I know of a few.
Rewire the arm with Brit audio
Use the Pete Riggle VTA Adjuster
and TWLs tweak: http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1032024188&openflup&121&4#121
Many posts are positive, so you might consider them.
Good luck.
