no there aren't, yes there are, no there aren't, no there aren't
lets educate:
1) all quality headphones are stereo
2) "5.1" headphones are $20-$30 gimmicks for kids who play counterstike to feel hip
3) stereo is just fine for music reproduction (oh by the way, 99% of all music is mastered in stereo, because the mixing requirement for 5.1 music is a pain in the @$$ (we're talking new equipment and a lot of extra work on the part of the engineer))
4) there are not 5.1 headphone amps
5) there is amplifier that accepts HDMI input, there are preamplifiers and A/V receivers with HDMI capabilities, but no amplifier in human history takes HDMI input
6) your question is pure crap, and you've based it on pure crap, garbage in, garbage out
basically, you want something that doesn't exist, because you want to upsample and mangle the hell out of your music with DDL or whatever (you show me a studio album released in DTS Master Audio, I'll give you a nickel), in reality, a quality stereo source and lossless stereo media (i.e: CD-DA, SACD, DVD-A, or flac/WMA Pro/etc) through quality stereo hp's will give you basically what you're looking for
as far as a separate decoder, I have basically the same thing linux is talking about (mine is Technics and black, and has a fancy remote, but it does the same exact thing, DD and DTS 5.1 from S/PDIF to analog, no HDMI inputs, thats generated elsewhere in the system (which I really really don't want to explain))
such a decoder will handle both 5.1 -> 2.0 conversion (at least mine does, and linux is saying his does as well), as well as stereo D/A duties (mine does, and I assume his will, if its anything similar) with PCM data
now as far as the whole "people content to stay with Pro-Logic", you're dead right I am, and I still enjoy my Laserdiscs as such, not to mention the half dozen or so DVDs I own that aren't stereo or aren't 5.1 (yes, I have DVDs mastered in Dolby Digital Mono, aren't infant standards fun to adopt?), and I also happen to enjoy my VHS collection in stereo, what a hethen I am for not burning it all to the ground and getting an 11.2 surround system for Bluray and nothing but
the truth is, there is no difference between "high def" formats and "normal" formats, lossy vs lossless is a different thing, DVD's can contain more or less lossless audio tracks (they have the storage capacity for it), not to mention that I doubt you're really able to hear the difference between ~768kbit and the 1411 its mastered in (who cares how good your speakers are, no speakers are "high def", its all marketing)
a "high def" format just adds more noise, and lets teach you how this work too:
its all about dynamic range, so lets look at 16-bit audio, which is about the limit of human hearing, because to get 16-bit audio reproduced properly, assuming it was mastered properly, you need about 100 dB of dynamic range (yay for half-assed appromixations to the nearest ten from a log scale), 24-bit requires something on the range of 120-130 dB of dynamic range, in other words we're talking about the ability to capture sounds like a 747 at 10 meters or volcanic erruptions from a mile or so off, and reproduce them 1:1 uncompressed, theres a reason those guys at the airport having hearing protectors on you know (not to mention, I doubt your speakers are capable of that, and I doubt your amplifier and preamplifier setup is capable of that kind of dynamic range, VERY little equipment can approach it, let alone actually attain it)
of course theres a lot of other factors that I'm far too lazy to explain, but the basic truth is, its just extra "noise" (theres a great arguement about this in a thread that member Patrick82 started about upsampling D/As for AES/EBU output)
so now back to whats been told to you for two pages straight: your question is invalid because what you're asking for DOES. NOT. EXIST. (but you don't care, and will continue to insist it does, and that we're just lying to you for some evil gain, really, why can't you just accept that you were mistaken?) and even if it did exist in some form, it'd sound like C-R-A-P

afaik this doesn't exist either, I know of a few BD players with 5.1 or 7.1 RCA outs, but none with variable, mostly because HDCP more or less requires the audio never be "user usable" as analog signals (so you can't pirate material you already own *rolleyes*), but it'd be quite interesting to see such a device (I can't even think of a DVD player with 5.1 variable output to be honest, I know of a number of CDPs with 5.1 variable outs, and of course preamplifiers with 5.1 and 7.1 variable outs via XLR or RCA)
not to mention that, as you said, "5.1 headphones are poop"
and for the record, an amp is not processing ,decoding, channel leveling, or applying master volume, nor does it give you preouts, its just applying (ideally) linear gain to a signal (for someone who is so eager to complain at technical inaccuracy in other people's posts, I'm surprised)
to clarify the "5.1 headphones are poop", the best example that comes to mind is the Zalman 5.1 headset thing, which is a two or three drivers per earcup, and even if you wired them all together, you'd still blow the thing up driving it from a decent hp amp, let alone from three hp amps (to get the "5.1 effect"), its just very low quality kit
