You've posited this argument in multiple posts and I've been unable to verify it anywhere else. I'm wondering if you could provide any sort of reference or white paper to support your assertion.
My understanding (from a Dolby whitepaper I read several years ago) is that the reason the LFE track is recorded -10dB was to provide additional headroom on the magnetic tape (film) sent to theaters.
That this LFE level carried over to home theater media (LDs, DVDs, etc.) was presented (at least in that paper) as more of an oversight or convenience than an intentional act. Since home theater receivers that decode internally are designed to reproduce sound from movies, the algorithms were designed to automatically correct for this lower level.
However, the multichannel analog connections on most receivers (and preamps) were originally designed for multichannel audio formats such as SACD (the subwoofer channel of which is mixed at the same level as the other channels) and thus no automatic "correction" was included (or needed).
I fail to see why boosting the signal in a player (after decoding and d/a conversion), then sending that boosted signal across a wire of a meter or so to the amplifier would be any different than sending the unboosted (but still post-decode and d/a conversion) signal across a wire of a meter or so, then boosting the signal before tranmission to the power amplifier (or amplifier section of the receiver). The signal reaching the speaker would be identical. If you are arguing that the amplification circuit in the player will introduce more distortion than the preamplifier circuit in the pre/pro or receiver, then I don't see how you can generalize beyond comparing a particular player to a particular pre/pro or receiver.
Now if you are arguing that boosting the signal in the digital domain might be superior to doing so in the analog domain, that's a different scenario and not applicable for those of us using a multichannel analog connection.
