Better DAC? Cirrus Logic CS42528 or Burr-Brown PCM5102

post #1 of 3
Thread Starter 
What is a better sounding multi channel DAC between Cirrus Logic CS42528 or Burr-Brown PCM5102? My HK 3600 receiver has the Cirrus Logic CS42528 and a higher end blu ray player has the Burr-Brown PCM5102 for analog outs. If they are comparable then I can save money on buy a lower model blu ray player and use the DAC in the receiver.

Neither.

In all likelihood, many of the features of your AVR work in the digital domain. Therefore, the AVR will have to redigitize any analog signal fed to it,* which means you'll be using the AVR's DAC no matter what. So you might as well use only the AVR's DAC, whatever BRP you buy.

There's often a bypass to this, but it bypasses those AVR features as well.

IME DAC suppliers don't lie too much about their products because their customers generally have the equipment to confirm or deny any specs they provide.

That all said, the Cirrus part seems to be generally superior, but not enough so that it would be audible.

I always favor leaving signals in the digital domain as close to the speaker terminals as possible, and that generally means buying a simple digital player with just digital outs and doing the conversion in the AVR. In many cases the AVR lacks a useful signal path that avoids its DACs, so you are stuck when them anyways. Most AVRs seem to have converters that are as good if not better than its amplifiers, anyhow so its not the DACs that set its performance limits anyway.
