B&W DM6, any good compared to speakers today?


I have an opportunity to pick up a vintage pair of B&W DM6's in great shape. How do they compare to todays speakers? I will be driving them with a Fisher 500C. I currently am using Kirksaeter 60's and some vintage AR 91's in my systems.

I have a pair of DM6 speakers since 1978. They are in good condition and still sound good with two Naim 250 power amps. I am looking to upgrade an old Naim preamp to the Townshend Enigma passive preamp and power source. 
Before any upgrade I would advise recapping the DM6s, after the capa are over 40yrs old now. I just replaced the caps in mine and honestly the upgrade bug is gone, a great set of speakers just moved into the "amazing" bracket. Well worth the expense and effort.
I have a pair and they are better than most, Like many of you iv'e had Proac super towers which in essence sound similar but more tunneled when listening to the DM6s these just expand the sound across the whole area.  It was suggested that some Monitor Audios might sound great but they hadn't listened to DM6. I am looking to recap these can anyone help?...  Thank you
I had mine out in the garden on the decking over the weekend... The neighbour popped around not to complain just to sit and listen to them.  3 hours later still sat there... though he had died but no he was blown away by the quality...
Just paired my Penguins with my 808's.  Definitely a difference between the two and together a totally different sound.  The crisp 808's tamed the lazy low end of the DM 6's but retained the boom.
