I might buy this Technics SL-P222 CD player (1989). It's almost as big as my turntable. And its $8   Is the sound from these SIGNIFICANTLY better than the sound from a portable SONY Walkman D-EJ100 (early-mid 2000s)   I'm plugging it into my Sansui receiver btw

I used to have Grado sr60i's. (sold them to a friend who is new to good audio)   I currently own Grado sr80i's.   I plan on selling them to buy Grado 225i's. (im getting addicted to the open back sound)   Are there other OPEN BACK headphones that you guys recommend?  Anything but...
