4Point9 vs. OL Conqueror vs. Vertere Super Groove HB

Hello, I was thinking that my next major purchase would be a tonearm upgrade from the OL Silver. My chain is Soundsmith Zephyr Star MC > OL Silver > Dr Feickert Volare > Decware Step-up with the ZP3 Phono pre > McIntosh MA 8900 > Belle Klipsch with upgraded crossover. I listen to everything from Jazz and Americana to Punk. I love the way the system sounds now, and would like to increase detail, realism and further tighten up the lower frequencies (and perhaps enhance), to get the best sound possible to the Belles ( which I got from a friend who's aunt was gifted the speakers from PK. ie. no serial numbers).

Since I have posted my system, I have added bass traps to the wall behind the system which helped clarify the muddiness. 

I am sure that I would be happy with any of the tonearms listed above, I was hoping to get some real world experience with those of you who have tried these tonearms either individually or the experience of comparing one to the other. 

I would also like to know if someone feels that I would get a bigger bang by upgrading the Volare to the Blackbird.

Thank you!
