please format your post, it's hard to read. Since I mostly stopped reading at your home theater setup I recommend you to get the Dali Alteco C1. I have them (also using the X3400h) and they are really great. Using Dolby upmixer or Neural X by DTS you get a profit in every game or movie that doesn't support Atmos or DTS:X. Soundstage is bigger, taller, it's amazing what they do with the additional height speakers. Don't get an internal soundcard other than for DSP tech like SBX etc. (get a Sound Blaster Z and use the optical out to your DAC/AMP) Save your money for a Schiit Modi Multibit + Lyr 3, get a headphone like the HD800. I mean, money isn't your problem as you said.
