Oppo-105 vs Oppo-93 + W4S DAC2 for stereo.

Hi,

I am confused between the following choices. This requirement is for best sounding 2 channel stereo.

1. Oppo-93 + Wyred4Sound DAC2
2. Oppo-105 (with same DAC chip as W4S DAC2 + digital inputs)

I already have an Oppo-93. Would it be better for me to sell Oppo-93 and get a brand new Oppo-105 or keep the Oppo-93 and add a Wyred4Sound DAC2 to it. Any body anticipate any change in the transport between Oppo-105 and Oppo-93. I know that Oppo-93 and Oppo-95 uses the same transport.

Thanks,
John.
