First experience as a lad going into a Hifi salon looking for blown 12" woofer for my Sansui speaker: "Those aren’t worth the postage to send them over here from Japan."
Second experience presenting my little 25wpc Pioneer receiver to a "tech" at a Kenwood amp clinic. Me" "Is this amp any good?" Tech (snarky, dismissive): "I think you’re about to find out!"
Years later, life pointed me towards a career in audio. I went in for an interview with David Beatty in Kansas City. Mr. Beatty was "the goto guy" for quality audio in the region. The interview was conducted in the "mad scientist area" of the facility. It was at the exact moment that David first fired up an new Nakamichi cassette deck, which he messed with during the entire interview. The interview was interrupted with David’s comments (asking surprised): "This thing is good! This thing is REALLY good!" His enthusiasm was contagious and may have helped push me along into a making my hobby my career for 43 years.
