Sweet Sweet Rig you got there. My Yammie 2020 is equivalent . My 1020 and Kenwood 7600 are inferior, but lets talk speakers. Love my Polk 10A’s and my Polk 7B’s and My NHT towers. The Klipch towers are too pingy for my liking but better than any Bose crap.
In the late 70s early 80s i worked for Rogers Sound Labs I had a pair of t Nevadas
I bought a Kenwood system from Costco about 1994 and it had what they called at the time artificial intelligence on the CD player. When you put the disc in it would scan the entire disc and automatically adjust the equalizer for each song. It was pretty to cool.
