I can’t drop any big names like you guys but Walt Lewsadder at Woodland Stereo was very kind to a young audiophile. If you know your history he helped Arnie Nudell with the Servo Statik loudspeaker system and sold a ton of them.
Audio people you've had contact with that proved to be good people.
Not just audio...but good people in many ways.... For me, Henry Kloss, Saul Marantz, Jon Dahlquist, both Mr. Conrad and Johnson, Harry Pearson and some others. On the opposite end, I did meet some large egos that have mainly faded into the walls.
