What are your Eureka Moments in this Hobby?

First moment, a friend returning my Led Zep 1 record the week it came out and he asked to borrow it. He came back over and said listen to it this way...handed me his headphones and plugged them into the amp. 

Fifty years later, hearing a hi rez digital version of Coltrane/Hartman and sensing the room and breaths. I had ignored digital until then.

@bdp24- You have a good memory for smaller details. I'm wondering--most significant/memorable improvements in audio equipment  happened in the 1970s?

a) The first time hearing Led Zep on my dad’s Heathkit and Scott kits he built.  This was 1969.  My musical life changed at that moment.

b) During that same year being given CS&N by a neighbor musician, playing the Garrard turntable, and listening to Suite Judy Blue Eyes.  Wow!

c) Roll the clock forward 30 years and the first time I heard Magnepan speakers.  What is this??

d) Listening to an external DAC for the first time (that I am aware of) seven years ago.  Amazing sound staging.

I remember these moments so clearly.

This year when my friend bought the audio mirror dac t3 for me and paid him back , it’s truly amazing . And bringing TS 75 and Discovery monoblock Galion amps.And when my friend let me listen to his analog set up, his set up made me realize vynil is truly good..Every time I played my 3 systems it’s a great moment.Going to axpona annually as well because I live 30 to 45 minutes from the venue.

Nice @swaudiofan !  Reminds me of my father taking me to Lafayette and Radio Shack.  And my Garrard TT with the big dark cover.... My friend and I split the subscription for albums, and we recorded them first play on my Teac cassette deck.  Cars and my van with 6x9 triax speakers.  Good times!
