Olness and Poris made totally sick tapes. I have a 10/31/83 Marin Civic that just frickin' smokes. Some others as well, my main source of auds back in the day were first/second gens from these guys. Had to buy a DBX decoder to realize the full potential. Now that I think about it, those tapes really sounded far superior to stuff that is getting transfered to the digital domain. I wished more of their stuff circulated.
