Sony Playstation 1 for a CD player ???

Does anyone know the difference between a model 1001 and a model 101? I picked up a model 101 today from my local pawn shop for $15.00 just for fun. It does have RCA connectors, but these are not on the back of the unit, they are on the end of the cable from the AV multi out.

Thanks,

Greg

Thanks Jaylee, The 101 is lacking a lot of detail and the highs roll off very quickly. It also sounds very closed in. It does have a smooth sound and OK mids for what that's worth. For $15.00 it was fun to play with anyway.
