The Oppo 93 supports only SPDIF and HDMI output but DSD is only sent out from the HDMI output.
The W4S has an HDMI-looking port but it's for I2S signals and is not compatible.
If you are using the Oppo to play back only CDs, the W4S+Oppo93 should sound similar to the 105.
But the 105 will also use the SABRE DACs for stereo SACDs and also multichannel SACDs/DVDAs/BRs etc.
