If going directly to amp, does it implement +15dB LFE boost?
1) Yes, 480i/576i, 480p/576p, 720p, and 1080i content can all by upscaled to HDMI 1080p output. This is true regardless of the source of the content. For example you could feed a 480i Standard Definition TV broadcast from your Cable TV box into one of the HDMI inputs, and the OPPO will upscale that to 1080p for its HDMI outputs. The same would be true for a 1080i HD channel broadcast.
2a) Yes, the players can be set to decode any content Bitstream they accept to LPCM for output on HDMI. Specific to your question, yes, DD 5.1 can be decoded to HDMI LPCM 5.1.
2b) The new players add DTS NEO:6 surround processing for 2.0 content played using the multi-channel Analog outputs. I'm not sure I have a handle yet on the detailed characteristics of that.
3) The players do not implement boost on the Analog LFE output (other than the usual Volume trim adjustment). The nature of the attenuation is a bit different from what happens in the 93/95. In the 93/95, +15dB boost (external to the player) is required to match the Analog LFE output to the other multi-channel Analog outputs regardless of the player's Speaker Configuration settings. This attenuation and boost is built in to insure headroom for the LOUD bass recorded as LFE, plus bass potentially mixed in as part of bass steering from "Small" speakers. In the 103/105, that 15dB attenuation and boost is still true if any speakers are set to "Small". However, if ALL speakers are set to Large (or some Large and the rest OFF) then the attenuation, and thus also the required boost, is only the standard 10dB inherent in how LFE is recorded. Typically when no pre-amp is used, the "amp" that the Analog LFE output is connected to directly is the amp built into your Subwoofer. And thus the boost amount -- either +10dB or +15dB according to your speaker configuration settings in the OPPO, is easily provided by simply adjusting upward the volume knob on that Sub.
