Audio Research SP17

Fellow Gear Fans,

I have the opportunity to purchase an SP17 in very good condition, gone over on a bench, for around $1,700.  I'd appreciate any comments, pros or cons.  I have two Pass Camp Amps that I can run as Monoblocks with it, if that would be a good match.  Other suggestions welcome.  Speakers I can use are Klipsch Forte II's with Crites upgrades or Heresy's -- both sets of speakers are from 1985 and 1987.  I also have Polk Audio 10B's from 1988.  Phono Preamp is KC Vibe, and turntable choices are Dual CS-5000, Rega P8, or Linn Sondek LP12.  Thanks!
