I have 2 Oppos in my setup
1. Oppo 93 for Living Room used with a LCD TV and 2 channel stereo amp.
2. Oppo 105 for my HT room used with a Epson TW800 and Denon 2310 AVR.
Reasons I went with Oppo
1. It can spin virtually any disc format, including VCD. VCD was a requirement for me as I have lots of VCDs especially the kids stuff

.
2. Twin HDMI. This was again very important for me as my AVR is not 3D ready and I needed 2 HDMI ports - one for HD 3D video and other one for audio
3. Decent analog sound from Oppo 93.
4. 2 x HDMI IN present in Oppo 105. I can plugin my HD STB and use Oppo as a 3D video receiver.
5. Superior analog 2 channel performance of Oppo 105. I know there are much better ACD spinner available but for the price vs performance, convenience, feature ration, Oppo wins for me.
6. Oppo offers above average or best picture quality and upscaling when comparing similar priced BD players.
7. External HDD support over USB and ability to process verity of audio and video formats including FLAC. A big plus for me.
I am yet to play Oppo 105 as its still not reached me yet.
Now Some issues with Oppo 93
1. Loading time is very bad. Even for a normal ACD, it takes much longer than other player. But once it starts spinning, its just fine. I heard that they fixed this in the newer versions - 103/105.
2. Analog audio performance from Oppo 93 is no better than cheaper Blu ray players. The DAC in Oppo 93 is no better or worse than the DAC in Denon 2301.
3. Long burn in time, especially with Oppo 105 on the analog audio performance.
In a nut shell, I choose Oppo for
1. Features an Convenience.
2. VFM (well this is debatable as some folks think that oppo is expensive. For me its still VFM as I got both of them from US).
3. Above average digital picture and sound compared to similar priced players.
4. High end analog audio performance from Oppo 105 for the money you pay. There are indeed much better performing ACD players, but you have to pay 2-3 times more. And you get lots of stuff from this single deck.
