Changing audio beliefs


Are there any audio beliefs you once held to firmly that you no longer subscribe to? 
I was an ardent believer in cables. I still believe cables matter but now not so much. Beyond a basic level of competence in the cable and connector, in my opinion, the rest is smoke and mirrors. Of course, it’s also possible that at my age (senior citizen) cables just do not matter anymore

Most of my beliefs... like that I could just apply intuitive logic to putting together a great system was destroyed in the first couple years of serious pursuit. I was trained and worked as a scientist, so at first I gravitated to measurements and numbers. I very quickly became disillusioned and dropped that approach. Learning from then on was to listen to systems and components... read professional reviews and learn as if I was building  new science based on observation. Then, I didn't have any more belief problems. 

At first I always wanted more bass.  Didn't matter if it was toneless one-note thumping.  More was better.  Gave that up as I learned how to listen.

These days I enjoy hearing most all recordings in any genre  for what they are.  Musical discovery!
 

Used to be I was way more strongly biased towards “audiophile” recordings and fewer genres.  These  days I still am biased towards high quality recordings to some extent but mostly with just classical music.
