OK, What do you exactly mean by HF capacitors?
I will be using separate buffered Vcc/2 supplies for every channel, and also a separate Vcc/2 to feed the headphone amps, because of current demands.
Every Vcc/2 feed will use 100K resistors and a filter capacitor from the center of the split. I have seen from 22n to 10uF to filter that to ground.
And there are very strong reasons for me use a single supply, it's not a whim or anything.
That doesn't mean that in the future we may not opt for a DC-DC supply, but not for now.
