oppo 105 vs 103

I have been interested in the oppo 105 to play cd's and sacds. In the latest stereophile Kal rubinson said the oppo 103 had good sound quality too. How close in sound are they? Those who have heard both please weigh in. I will be using the player in two channel stereo only and would like to save some money if they aren't night and day. my systems equipment are rogue metis preamp, vincent sp331 power amp, von schweikert vr3 speakers cambridge azur 640c cd player, and pro-ject debut carbon turntable.
