Just getting started,I have purchased 2 sets of KG 4 ,and a HK 630 on E Bay,have not received any of them yet.Wanted to introduce myself. I had a system with an old pair of Bose 601's that I bought back in 1978,I used to have a Sansui G 5500 that I bought at the same time. I presently have a Sony STR -D915 that I bought in 1994 or so,and another set of older pioneer speakers. Is it possible to run 2 sets of speakers off the HK 630 at the same time? I do not think so,but thought I would ask
