B&W Signature 805 vs Dynaudio SE 25

Hello.
Please I would like to ask you differences about these two speakers (advantages, disadvantages, which speaker is better and why in all frequencies range-from low to high frequencies). I listen almost to jazz, vocal jazz, 60's,70's,80's,country music and classical music.
I read, that Dynaudio SE 25 is better in low frequencies, B&W signature 805 in mid and high frequencies.
