Which sounds better: I2S or Coax.

I will be using PS Audio Perfectwave Transport and DAC.  Thanks!

Paul from PS Audio is pretty clear that they consider the I2S to be superior.  Any reason to question them if you trust them enough to own their equipment?

The quality of the components and implementation is everything. Early versions on a new connection standard is something to be considered as a requirement years after it becomes a standard. So, for today I would concentrate on the sound quality of the component… and use the best connectors available… AES or SP/DIFF.

If the DAC is designed properly, the interface will make no difference. I2S is another way to extract coin from your pocket.

Hi RSA -

If you will be using PS Audio, you can only use I2S if you wish to access everything  that the PSA transport & DAC will offer. Period. End of Story.  This is how PSA designed its components to work.

The SACD handshake will only occur properly using I2S, assuming SACD playback is important to you. Be aware that not all I2S (HDMI) cables are created equal. Also, you will need HDMI, as opposed to HDMI 2 cables.

Follow these rules and you will be rewarded with some very nice equipment and sound. I have the Stellar Gain DAC & Perfect Wave SACD Transport talking to a Rogue Sphinx integrated and Zu Audio Omen bookshelf speakers. I am using an Audioquest HDMI cable. Check out the PSA Forums. Lots of threads on the subject.
