Your "eureka" analog moment


In the beginning I had a succession of crappy cartridges. Back in the day (1970's) you could buy a turntable and they would "throw in a cartridge " for next to nothing. 

Had ADC, Empires, Stantons, etc. Nothing above $30. Decided to invest big bucks - $65- for a Shure V15 Type 3. Oh my- my records never were so good after that! That was my moment, and then when a friend loaned me Discovered Again (Lab 5 on Sheffield) I was amazed.

Too bad I no longer have the V15 type 3. Over 20 years ago, missing a stylus, I sold it to someone for I think about $30.

When a buddy lent me his Rega P2 and some uncleaned lps and the sound completely bested my 5k digital setup.
I remember thinking "aw crap. now I have to build a whole analog system" :)
1000 lps, rcm, tubed phono preamp, vibraplane, Basis 2800, Dynavector XV1s, etc, etc later... So much happier.
Hm, tough question...maybe the moment when I listened the first time with a FR-66s to a Koetsu Coralstone with Diamond Cantilever...
 I've had several. As far as equipment is concerned, the latest ones were when I switched a rega (300) tonearm out for an older Victor tonearm (about 2 years ago). Had it again switching that tonearm out (last month) for a Pole Star. As far as albums are concerned, the eureka moments happen all the time.
