choice between origin live tt or vpi aries or avid

plse help!i have to make a choice between these 3 used tt.

origin live, vpi aries, and avid volvere.

I am currently using a notthingham horison tt with rb 250 arm.
Is an upgrade really necessary? If yes what would be the best option long term?
Can I do something to better the sound of the horison?
and secondly, if I have to choose an option from the above 3 which would you guys/gals suggest, and with what cartridge?
I am using currently a dynavector DMK11 with the horison, and the sound is good.

Tks in advance for your help
I've owned a VPI Scout and an Avid Diva II, and the Avid kicked the Scout's butt IMHO.

I'd definitely pick the Volvere.
I own none of those , but would say either upgrade the arm on your current table to an REGA RB700 (I believe it would be a direct replacement) or buy the Volvere.
I own Rega P5, and a Kuzma with Stogi S.
I would buy a Diva anyday.
I had a Scout and wasn't in love with it. I currently own the Volvere which is excellent and will be updating it to the new version Sequel when funds allow it. Very quiet table, rich and dynamic. For reference I use it with an SME V and a Koetsu Onix Platinum.
get a better arm. Despite the unquestioned value of low end Rega arms, they are only the tip of the iceberg or what is possible.
I own an Origin Live Resolution with Illustrious arm. DELICIOUS! The ZYX tops it off.
