Bur Brown vs Wolfson

[Drew664]

Which DAC is better?

I was looking into the Pioneer Elite line of receivers and I was surprised to see that they use Wolfson instead of Bur Browns. Like many others on this site, I'm learning from those that know just about everything A/V related. This is something that isn't discussed much, but from what I can gather Bur Browns is a highly desired DAC, but is it better than the rest?

Any insight into these would be helpful to myself and others that are looking to invest into an A/V receiver.
