I am going back and forth. I have Ebay watches on two receivers that interest me, one new and one from the 1970's. The new is a Harman Kardon 3490 and the vintage is a Pioneer SX-1010. I've read lots of older posts, both items are in high regard. I will be using the receiver I choose with a pair of Klipsch KG 4.2 speakers. Any advice to steer me? I am at the point of a coin toss to decide. If there is a better choice or opinion I'll listen! Thanks.
