Actually Thiel CS2 thru 3.5's would sound great with your Pioneer - I know from experience with my SX1050. My gf now has it with a pair of Meadowlark Kestrels - all purchased used here on the site. I love the Pioneers.
ADS as well. Had those with a Marantz 2250b receiver. I've avoided "vintage" AR's and the like simply because most of them appear more compromised than the others I've mentioned, and purchased. Klipsch Heresies sound great on the old receivers as well.
There is some thinking that the old receivers sound "old", but to my ears they simply sound different. Any piece of equipment that's 40 years old and still sounds good deserves respect! Good luck!
