Putting a fet after a tc9237 dac

[srinath]

I have an onkyo cd player that has a tc9237bn dac chip in it. I'd like to put a fet output stage in place of the opamps like this guy here -
Fet-ishizator

Now the tc9237bn is a voltage output dac, but I know nothing else about it. What circuit should I use, he says I should modify it for a v out dac, what is the right modification.
BTW can I just send the output of the dac to a capacitor and to the output, after all it already is voltage, so it will just go out as pure ac voltage. If yes, what should the cap value be ?

Thanks in advance.
Cool.
