Although our paths didn't cross as often as I would have liked, I am very sad to hear of the passing of Ken Ishiwata. He leaves a legacy in the development of Hi-Fi products few others will ever match. RIP.
Only last weekend I took my PM66 KI out of storage (after 6+ years!) to power my front speakers. I had forgotten how it was to just pick an instrument and follow it, then pick another one and another! Quite a legacy to leave behind - his work brought pleasure to many and continues to do so, can't ask for more than that really...
I've owned about a dozen Marantz kit:
SR 19, SR 18, SR 12 SR 7010 AVR, the DP 790, 3 KI CD players, two amps, one NA 11 streamer and even tried their speakers and mini system... the 63 KI CD player is still my favourite, even though the CD mechanism gets stuck after a few years..
