which amp would the better amp for jazz, blues, prog rock, classical, orchestral and electronic music?

I have been narrowing the second hand options for a speaker amp and landed on two main options:
the naim 5si for 1000 usd.
or the vincent sv-500 for 650 usd.
the chain is zen streamer-> zen dac v2-> amp-> elac carina bs243.4

which one of those two would be the best for me? personally, I like warm sound that does not result in the absence of detail, imaging, dynamics and richness. 

and the system will be put in a non-treated L shaped mid-large sized living room. (the picture I added is not my living room but damn near close in shape)

thank you for your attention, looking forward to your replay <3

Can't say I'm a fan of Vincent Audio products. Naim on the other hand always satisfies for musicality.
