Yeah, understood. It's all pretty crazy, but most agree that a good ripped CD played thru the same dac in the CD player will sound better than just spinning the disc in the drawer.
There are many threads that you can read archived here that explain in gory detail, but to summarize: just rip a CD into your mac or pc, download a trial version of audirvana+, Amarra or Pure Music. connect computer to one of the digital audio inputs of the Oppo and you can listen for yourself. Cheers,
