KEF reference 207/2 vs DALI euphonia MS5 anyone?

Hello everybody )
My system
PS audio perfectwave dac mk2 + transport
PASS x350.5 amp
Now I should complete it with speakers and I have good offers for dali ms5 and kef ref 207/2.
Unfortunately I cannot audition them ,so it will be a blind shot...
at this price tag I can buy Dynaudio C4 also...
prices for them
dali ms5 -4400 euro
kef ref207/2 5300 euro
dynaudio C4 - around 5400 euro.
I listen mostly electronica, house , classical and rock .
my room is around 20 feet L x 13 W x 10 H ,BUT I listen them on the long side around 11-12 feet from the front wall.I will consider room damping very very soon.
any thoughts will be highly apperciated.
cheers to all highenders!
