The Wired Mixamp is easily the best solution if you have multiple hookups:
RCA input for the Wii (it works wonderfully)
Optical Input for Hd system 1 (for example PS3/360)
Digital Coax input for HD system 2 (buy a simple digital coax to optical digital converter, which will give you 100% the same sound as the optical digital input. (Note: whatever is hooked up to the optical digital input on the Mixamp gets priority over everything else, in case you like having multiple systems on. You won't be able to hear the other inputs until you turn off whatever is hooked up to the optical digital input)
The wired Mixamp is kind of clutter heavy especially if you plan on getting a digital coax to optical digital converter, but it is the most versatile in terms of what you can hook up to it.
The next iteration of the Mixamp BETTER have multiple optical digital inputs... I swear. With my 5.8, I have to reach behind the Tx unit and swap optical cables whenever I wanna change from my PS3 to 360 and vice versa. All the optical switchers I used didn't work properly.
I'm pretty sure the Wii in general does a simulated 5.1 DPL II. But doesn't the Wired Astro only do DPLII'X' instead which would convert 5 channels to 6 or 7? eek! :p
Anyways, i wouldn't be using this for my PS3/Bluray/DVD or music just the Wii and that's that, so no need to worry about an optical cable, although i have one around here somewhere for my PS3, but I've switched to HDMI for sound since that gives my 7.1 receiver 96hz/DTS Master HD Audio for Bluray movies and yadah yadah hehe....Not sure if an optical or HDMI connection would make a difference when it comes to using headphones though. And i hear the new wireless Astro supports a higher frequency, too bad it doesn't support RCA cables. Sigh* If only there was some sort of RCA to Optical Adapter.or is there?
Anyways, when you say that the DPLII from the Astro for the Wii sounds processed, do you mean how the Astro deals with the audio? or just how DPLII for the Wii sounds processed in general when using a surround sound system? By no means does it sound as good as Dolby Digital, but it's still awesome to hear that full 3D world of sound in Super Mario Galaxy for example....Hearing goomba's running up behind you or a water fall pouring to your rear/right is pretty spectacular and quite immersive.
But ya, I'd be totaly crushed if the Astro Mix offered inferior 2 channel sound(for ex) compared to using my 7.2 Receiver. I don't think i could settle for anything less, just more with the flippin' inclusion of the Astro's ability to pump out surround sound in your very own headphones. 
Ugh! If only my Walls were ultra sound proof, then i could actually use and blast my 5.1 surround sound system for gaming and movies. But for now I gotta settle for headphones. I'm still incredibly stoked about getting my HD380's.....Hardly any sound leakage and you get Isolation, hell yes! And superior bass compared to the HD555's which i also have....But I'm worried that the 380's sound stage won't quite be as nice, but close.
