Hey folks,
I am building a surround sound amplifier to go with my silent Home Theater PC.
I am using a Creative XFI sound card as my surround sound decoder.
I plan on having 8 channels of audio for 7.1 sound using a set of Tripath TAA4100A amps.

There may be two extra 25-watt channels using a TA2021B chip.
The two extra channels are to run a set of Bass Shaker transducers I have. I may just omit them however and use a AMP3 kit.
I already two AMP3s kit in my Car, and I am very impressed with the audio quality. And that is why I am sticking with Tripath amps.
Here is my planned layout for the chassis:

(The area at the far right is for a A/C input module)
The front panel is made to match my existing themed HTPC:

The front panel will have a single LED that will change based on MUTE, SLEEP, and POWER.
The faceplate will be wood on my model, but plastic if I build more.
Behind the power button will be a touch-sensative mute circuit that will allow one touch muting and mabye a hold-to-sleep setting. Normal volume/mute will be controlled by the HTPC via remote.
I may do a group buy later, depending on how much parts cost.
Since most of the schematic is cut and paste I will be releasing the design files for the PCB and schematic.
Right now I have a schematic with the stock parts that Tripath lists in the TAA4100A spec sheet.
I haven't designed the PSU yet. I am tempted to use a commercially made open-frame PSU that can put out the power needed. Rather then build my own.
Does anyone have any suggested changes to any of the component values? Besides the standard high-quality parts.
