Default My TAS5630DKD PCB

I have been doing a lot of reading about this Class D chip. I decided that the EVM was a little expensive and I was not a big fan of the EVM pcb. I had pleanty of free time so I decided to take a shot at making my own pcb.
The pcb was made in Eagle and checked with Viewplot.

It pretty much follows the EVM design with only a few differences.
Minor movement of components
Mounting for Intel P4 heatsink
Screw Terminals vs RCA & Banana Plugs

Please have a look at the layout and give feedback. Thank You.

After checking the board and schematic a few more times I will order 5 prototype pcb's and assemble. Hopefully it will work with good results. I made sure that the SMT inductors had very high saturation currents (21A). Hopefully the build will have good results.

The default of Fosc is 4Mhz. The EVM uses the default master. Do you see any issues with this? The PCB has the option to add a resistor to change the frequency.
