I remember the DQ-10. I was a salesman in the 1980's in a mid to hi-end audio dealer,. Good speakers; but, somewhat awkward to set up, and the their stands were crap and did not support the speakers very well.
By way of suggestion, don't get caught up romanticizing a speaker whose design is close to 40 years old. Occasionally , . you will see ads on AG for updated versions of the DQ-10's, or even the so-called DQ-20 ( or DQ 30?) which was more or less a flop.
Use that 2K to 3K money looking for a used pair of Vandersteen 3A's or Acoustic Zen Adagios, or one of the lower tier Dyanudio Contour speakers, a (used) pair of the newer Quads speakers, or Martin Logan models "Aerius",, "Ascent" or "Vantage" They should provide superior sound quality and much better tonal accuracy than an updated version of the DQ-10's
Good Luck
