Default DX Amp PSU with DC Protection

I created an power supply to power my DX Precision I amp. I want somebody to check it over to make sure it works before i etch it.

It has a regulated VAS power supply,
Crossbar protection across the V+/-, (DC Offset)
Turn on/off pop's eliminator

Is there any audible benefits of building a PSU for each channel of the amp?

The DC offest protection here is different to the one you just posted on your other thread.

As regards speaker protection it is just not sensitive enough...
