^ well according to the 1/8th guideline, it probably wouldn't be the best match.
I really dont get why Creative was ok with such high output impedences? Did they assume everyone would use 100+ ohm headphones? Thats pretty ridiculous.
Pardon my lazyness of not having read everything but does the SBZ not behave like the X-Fis (TiHD in my experience) as in going from lineout -> Amp will still give you every headphone feature if you set to headphones?
I'm running mine to my DAC/AMP and do notice differences between speakers vs. headphone during gaming. When using headphones the speaker option is of no real use at all and sounds weird.
No what I found was while sbx surround does behave like CMSS3D's different modes, they are not selectable by the user or from which output they operate.
ya check my last few posts on why speaker sbx surround differs from headphone sbx. It works the same as CMSS3D Virtual and Headphone.
