Don't know about DefTech but NHT to my taste is complete decline from the real music neither electronic nor acoustic. 803's or any B&W line would mostly need the help of sub.
They're most defined in midrange and upper detail. Positively 803's will have substantially less fatigue at loud volume levels vs. 685's. To get rid of sub within $3k I'd recommend researching and/or trying if possible Sonus Faber, Thiel or Totem.
