I could use some help. I have found two separate pairs of speakers : Bowers & Wilkins DM650i and Paradigm Monitor 11 v3. I would like to upgrade from my Polk TS towers. I’m a rock, jazz, blues guy and just want quality sound for my enjoyment of these genres. I push a vintage Marantz or a Yamaha CR-1000. Which is the best option for this? Price of each pair is pretty equal (they are both used in excellent condition).
