This price is the product + shipping to Brazil final price. The prices i put are from Ebay, the best from sellers who ships to Brazil. About DSS i don't care if is new or used, but it's hard to find these things on Ebay.
I think that the use will be 75% for movies and 25% for games, and at first post the OP have a good impression for it, i don't know if have best headphones in this price range for general use...
I have a X-Fi XtremeGamer on my Desktop, but i bought last year just to use DTS Connect to play/view 5.1 movies on my HT, because it has only 1 Toslink input. Now my desktop is a HTPC, i don't use it more (audio goes trought Nvidia GT520 HDMI).
Sorry for bad english in any post, it's not my native language. The question is that i have a notebook with P2 and HDMI output, so if i want to output any 5.1 sound, or i will have to buy a X-Fi USB card that makes a Dolby Live, or output from HDMI.
I want the headset + amp (DSS, ax720, etc) to see movies on my notebook with Dolby Headphone audio, and to play Wii (RCA audio, easy to convert to P2) and Xbox (optical), so this DSS will take the Pro Logic II from Wii and Dolby Digital from Xbox and output to Dolby Headphone fines. And from notebook, i will need to use Media Player Classic to output the audio on Dolby Headphone, and with the DSS take the DH audio from P2 and output it on my Headphone? Or i just plug the headphone direct on notebook?
Dolby Headphone by DSS is the same DH from software? (Foobar, MPC)?
About DSS, i took a read on DSS manual, it says that it can take audio from USB, but only stereo.
Sorry for a lot of text and questions, and any question about "language barrier making not know what i'm saying", fell free to ask and i will try my best to write again, being "clear".
Once again, thanks a lot for attention.
If you think you write a lot of text, you should see some of my posts
So you want to get virtual surround with a desktop HTPC, laptop, Wii, and Xbox (360 with HDMI?). The computers both have HDMI (which I assume is connected directly to a Tv?), but the laptop has P2 (dunno what this is, someone else probably does) and the desktop HTPC has a toslink/optical in (no toslink/optical out?). Does your TV have an optical out? Most modern HDTVs do, and that could of course connect to the DSS. Oh, and the DSS implementation of DH is like DH mode 2 on Foobar.
When you're on your laptop... Well, I guess the stereo out could be up sampled by the DSS to Dolby Pro Logic II simulated surround and then turned into Dolby Headphone, but you'll lose a lot of positional cues. You might do well to find a DH plug-in for Media Player Classic, or find the Foobar program and get the DH plug-in for that, so you'll have good DH when watching movies with surround. The only thing is gaming on your laptop... If the game doesn't have a Headphone mode built in, then DPLII-->DH may be the best you can do with a DSS.
Your desktop HTPC with X-Fi XTremeGamer should still function even if you are using the graphics card for video out. So you should look into that.
Wii would have to be DPLII-->DH, using whatever method of connection to the Wii's stereo sound you can manage.
Xbox optical will be easy to get surround sound with DSS, also works pretty well for DVD movies and Netflix too, in my opinion.
Another option IMO you could consider that would do virtual surround for headphones, if you can find a good price, would be Creative's Recon3D USB sound processor. It's what I use... Mad Lust Envy (the OP) prefers his Mixamp, I prefer the Recon3D to listening to a DSS I heard at my local electronics stores. It's priced between the DSS and the Mixamp, but the benefit is it can act as an external soundcard through it's USB DAC, Optical Input, and 3.5mm Headphone Input (you can get an RCA to 3.5mm cable for your Wii). So you could just run everything through it. Just an idea, good luck!
