I have a PCM2902 that I'm using between the computer and my Sansui integrated amp and I love the way it sounds.
I built it around the TI datasheet...it uses an LM317 for the supply, rather than the USB bus.
I'm simply using 10uf caps and some 100k bleeders on the output.
What is the (real--practical) value of having an opamp buffer stage on this chip?
I mean I know the theory of less loading but is it a problem with the PCM2902?
I suppose using an opamp gives you the ability to "tailor" a sound?
I believe in no frills -- but is an output stage a "necessary frill"?
Thanks.
