Quoted from chillme:Looking at the Pinsound XL card, it has two HDMI ports, so it's a bit different than the standard boards.

I have a pinsound in my TZ and it helped pump up the sound since it has adjustments for treble, mids, bass.
I have PinSound for both my TZ and IJ. Sound adjustments can be made on the sound card. Depending on the machine, there are diferent sound compiles that other people did and you can just down load from PinSounds web site.
Hope this helpd
