A person I would like to thank/mention in the history of the high end,

The designer of my dac Christophe Mariac.....Starting point system NOS dac....It is very difficult to create a low cost dac with more than great S.Q. I dont think if cost is in the hi-end equation tough that my dac is one contender in the hi-end field...

BUT my amplifier designer, beginning with high quality transformer,
Mr. Sansui was.....😁


«The company was founded in Tokyo in 1947 by Kosaku Kikuchi, who had worked for a radio parts distributor in Tokyo before and during World War II. Due to the poor quality of radio parts Kikuchi had to deal with, he decided to start his private radio part manufacturer facility in December 1944 in Yoyogi, Tokyo. He picked transformers as his initial product line. Kikuchi’s thought was "Even with higher prices, let’s make the higher quality of products.» WIKI.

@bdp24 yep

Tom Fletcher - Nottingham Analogue Studio turntables.
Flemming Rasmussen - Gryphon Audio.

Neville Thiele and Richard Small who changed speaker design from guessing to a science and vastly moved development forward and made it more accessible.

Cutler (Bell Labs) who pulled together many of the concepts necessary for sigma Delta ADC and DACs including noise shaping which eventually lead to the far better studio ADCs (and most DACs made today).

Toole for relentless pursuit of what really matters in speakers and has likely influenced most modern speaker designers.

John Mullin who took German WW2 basic magnetic tape technology and "perfected" it to create a giant leap forward in audio recording capability.

Dolby for professional noise reduction.
