.
with for a day (from the audio world - either production/design/theory/tech) ... to experience/learn what you could from that person ? why ?
I was going to say "pick one" , but that's not really possible ..so limit to 5 or so.
Was thinking about my own answer to this question and came up with
George Martin , the Beatles producer ..he really shaped it. So much to learn from him.
George Harrison , in addition to guitar , he was an amateur race driver. some beers and a fun day.
Thomlinson Holman ...THX , I read his manual on my AptHolman preamp and he has an interesting and informative style that was enjoyable. So much to learn there.
Edgar Villchur ...incredibly smart audio inventor. One of the pioneers.

Am sure that many other names will pop up as this gets thought out further ...
Who would you ?
