Speakers that work in a medium room to match Krell

Looking for speakers that can work within 10-12 inches from the back wall, my listening area is around 12'W x 22'L x 9'H. I listen around 80% to jazz/vocal and 20% to both pop and classic, in a moderate volume levels.

I prefer focused detailed presentation, without an upper midrange glare and boomy bass, on a soft, smooth and warm presentation.

The rest of my system is Krell FPB 400 amp + KPS 25Sc preamp/CDP and Transparent RXL-MM/Cast cables.

My preferences so far are as follows (not in a special order):

+ Avalon- Opus Ceramique
+ Dynaudio- Confidence C2
+ Wilson benesch- A.C.T
+ Wilson- Sophia
Monitors like: JMlab- micro utopia Be, Dynaudio- C1, SF- Guarneri plus Revel- B15

Which one of the speakers can work close to the back wall and match best to my room and the Krell's?

Thanks for your ideas and suggestion.
