Digital Front End with Vintage Preamp/Amp

Please excuse what might be a naive question from a new member, awakening from a "25 year sleep." I have a decent 1980s era system (ARC SP-8/D-90 preamp/amp, Linn turntable, Magneplanars). Its time to add a CD player. Will all modern CD player work with the SP-8, or will I have to deal with interface problems? (You can see that I was "sleeping" with my analog system for a very long time, but I can no longer avoid CDs!)
All CD/DVD/SACD/DVD-A disc players have regular stereo analog outputs that will work with any line-level input you have on the SP-8.
