Since the 717 is a brute of an integrated it will match well with most speakers. It is a little on the dark side, so it may pair well with a set of speakers that are a little on the bright side. I have one that has been fully restored, including all electrolytics, etc. It has sounded great on every speaker I have paired it with. That would include Dalquist DQ10, Mission 770 and KLH 6. The Dalquist were the toughest load, and the 717 handled them well.
I listen to a lot of classic rock, jazz, and classical. Sounds great all around.
