johzel - I own both of these transports. I use the Pro-ject CD Box RS.
The Pro-ject, in my set up, sounds more detailed and neutral. The Woo has a more weighty, analog sound which is very nice.
Both have AES/EBU and S/PDIF outs (and optical). The newer WTP1s have a BNC connector instead of RCA (mine is older and has RCA)
The WTP1 remote does not have direct numerical access (The Project does). I got used to it and it wasn't that bad.
I haven't tried the WTP1 with AES/EBU. I'll have to do so.
Both are very good.
