I just upgraded my old CM Storm sirus 5.1s to a pair of BD880 Pros, Just as a side project to have a bit of fun I am looking to take advantage of the opertunity to get the most out of my old headset and SBZ soundcard. So im looking for a bunch of high end 30mm drivers a pair of 40mm subs and some upgraded wireing for my old headset, somewere in the range of 250+ohm and good quality, Seeing how im planning to stick to the original true 5.1 design of the cans, just upgrade them, im looking to make sure I can drive something like that first, the SBZ haz a 600ohm amp but only on ste single headphone port, are there any true 5.1 headphone amps out there? something with 3 analog inputs a amp and 3 analog outputs (Front L/R) (Center / Sub) and (Rear L/R). anything like this exist? Because its just for fun im looking for sound quality, but I am on a Budget, Any suggestions so I can have 1 amp instead of 3 would be great. Also any other recomendations for things like drivers and cabling also welcome.
Any phisical 5.1 headphone amps out there?
Gear mentioned in this thread:
No such thing, except for what I think comes with that Storm Sirius, assuming it actually does use several drivers for true 5.1 surround. Even if you do find one, or reappropriate the Sirius amp module, how will you build a headphone chassis that will accomodate at least four of those 30mm drivers (with a phantom center) and a 40mm bass driver? You might as well get a motorcycle helmet and mount them there around your head.
The CM Storm Sirus Actually already has 3x 30mm plus 1x 40mm per side, it would only be a bit of modding and replacing, not the only headphone to have that layout either, the turtle beach Z6A uses the same setup heres an example of the Sirus
I'd probably build that inside a helmet. It might have dedicated drivers, but they aren't as far apart from each other for each ear to hear each as coming from front, side, and rear-side. Basically it looks like it'll have to be six drivers for the 5.0, surrounds slightly off to the rear of the ear lobe, mains and centers slightly forward. Bass driver can be mounted on top if it's a helmet. As for the drivers, I wouldn't know where to get drivers that size. Parts Express has 40mm drivers but that's all I'm aware of, short of ordering spares from Grado or Sennheiser. Then again maybe you can just source drivers and mount them in the Sirius chassis, but again it's the 30mm size I'm not sure where to get. I think the KSC75 uses 25mm drivers, and if so, there might be some kind of adapter somewhere (just not necessarily audio-specific). Dampen the chassis and the mounts, if possible you could even try to isolate each driver with a tube shroud, and drill the cup covers to effectively have the drivers operating as open-back cans while keeping the bass driver in a sealed enclosure.
As for the amp, if you want to use anything other than the Storm Sirius amp, you could ask builders here to make a custom amp, for example using O2 amp modules, and just as important, a power supply that will power all of those. Have a master preamp controlling all of them, but check if the software on your soundcard can tweak the gain on each channel pair.

the hd 600 uses 30mm and I can get replacement drivers for about $50 a driver from Sennheiser, They will require some modding to get them down to the driver to fit, I wouldnt be against getting a custom amp / power supply, any artison recomendations? The sirus Amp isnt terrible, but the DAC is... I want to be able to use my Sound Card for the DAC.
Are you sure about this? AFAIK they have 50mm drivers. Well regardless of the actual size you'd still have to cut away the rest of the baffle.
One of the better known names here is MisterX; you can shoot him a PM and see if he's got free time for this.
