Recommend a budget floor standing speaker less than $1,000

For the money I think Vandersteen is an excellent speakers

old Alon speakers 5's MKII for larger rooms, model 2s for smaller room.  Happy Listening.

34dean, as one who has contributed throughout your other thread, I must agree with akg-ca. The only thing I can add is that in your price range I believe I could find a more satisfying bookshelf speaker than a floorstanding pair. Quality stands need not cost that much. 

Being "blown away" is completely dependent on what you currently have. I was blown away when I upgraded from my boombox cassette player to an all in one turntable/receiver but separate speaker set up. That was 45 years ago but the feeling is still fresh as yesterday. Nothing wrong with the NAD3020 but you better stick with 8 ohm dynamic/cone driver speakers with an efficiency/sensitivity greater than 90 dB. As being blown away, you'll need to be the judge of that.
