b&w 805d2, d3, pm1, and others

hi, there,

i am thinking of getting a new bookshelf speaker. there are couple speakers in my mind
 
b&w 805d2, 805d3
b&w pm1, cm6 s2
pmc twenty.22
psb synchrony one b
focal aria 906
kef ls50

those speakers are not in the same price range. it is used for classical music (large orchestra works). i am looking for a pair with possible best performance/price ratio. getting a speaker like cm6 s2 would allow me to stay comfortably within my budget. as i am new to audiophile, i am not sure should i go for little bit more high-end, or just stay in entry level. i wonder if extra budget (805d2, d3) actually makes the difference, i would go them. thank a bunch.
