I second mizike, it was Knowledge. Which led to better speaker placement, then a multibit external dac for digital, a tube stage in the chain with the right tubes, an amp that was a good match for my speakers, the right interconnects, proper settings on my pre, and impedance matching for system synergy. It finally all came together for addictive sound.
Your first component that was "special"
I got into hifi 40 years ago. I had a Pioneer receiver, Kenwood table, various entry level cartridges (ADC, Stanton, Empire) and Studio Design speakers. I wound up buying a Shure V15 Type 3 cartridge. That was the first piece of gear I bought that was way beyond ordinary. I had kept the cartridge until about 2o years ago- I sold it because by then no decent replacement stylus was available. Wish I still had it.
