Ken Ishiwata – One Heck of an Inspiration (Photo courtesy - Stereonet) When some of the team at AMR were ‘growing up’ and heavily involved in listening to CDs on the Eighties, we fondly recall the hot-rodded Marantz CD-63 MkII and KI Pearl Amplifiers. They were machines we lusted after as they were unobtanium. In the digital realm, guided by Ken Ishiwata, there were: Marantz CD-7 CD-12, CD-17, CD-45, CD-50, CD-60 and many others that all had at the heart the ‘King of MultiBit’, the one and only TDA-1541A. As we approach 2020, when we listen to the AMR CD-77 with the TDA-1541A, we are still in awe that this chipset still compares to the very best digital has to offer. Despite its approaching 40 years old! Along the way, we have Ken Ishiwata as one of the key inspirations for AMR to thank for guiding us on our digital journey. Ishiwata-san, thank you very much for your input in the audio industry. You will be sorely missed.
