Speaker upgrade from SP-BS22 options? Kef350 vs Diamond 11.1?

Hi all, I recently decided to upgrade my PC, and fell down the upgrade rabbithole so ended up buying a new receiver as well (Yamaha rx-v485); so now im also looking at speakers. I've looked through a lot of posts and forums to find out what new options have turned up but now im at a crossroad between a few speakers. Currently I'm running a 2.0 setup, but once I purchase the new speakers I will relegate the Pioneers to surround and use both pairs as a 4.0 setup.

My short list is currently:
- kef q150
- kef q350 (only 60usd on top of the q150 which is making me contemplate these instead)
- used kef q100 (270usd on australian equivalent of craigslist)
- wharfedale diamond 11.1
- wharfedale diamond 220
- dali zensor 1 (refurbished but it seems quite outdated and is also at the same price as diamond 11.1's)

Room is moderate sized at around 6m x 4m; 24m^(2). The speakers will be placed as a nearfield setup on the desk, as the receiver is hooked up to my PC and consoles.
My main priority will always be music. Maybe an 80/20 ratio of music/entertainment so musicality will always be the deciding factor. I have heard that Kef's sound signature is more neutral with the diamonds being better suited to music as they are warmer. However, Kef's are said to have better soundstage and imaging, in which case, is just as important for music.
