I have the same setup and I use Tekton Pendragon and totally love them. I'm hearing incredible things about the Double impact as well. They are big and you need to have the room to place them, also they may not be wife approved if that's a concern.
Floorstanding towers
I'm currently in the market for some new towers and have a few I'm looking at but am open to suggestions. I have my ways on the monitor audio bronze or silver series and the Martin Logan motion 40. I have also heard and like paradigm monitor series speakers. They will be paired with a parasound halo integrated and vinyl as well as streamed music will be the main source of sound. im open to ideas on other speakers in the 2-3k range for the pair.
