I echo what geebo has said, try both methods and choose the one that you prefer. That's exactly how I have my ERC-2 connected (AES/EBU and Reference Analog).
A digital connection gives you two options... Stereo (with bass management and the options of Dirac, PEQs and/or Loudness Compensation) or Direct (bass management only). Of course you also have an assortment of other "Modes" to choose from.
Reference Analog will give you what comes directly from the ERC-3 in all of its unadulterated analog glory (no processing options whatsoever).
FWIW, "I" prefer the digital connection (Direct mode) simply because "I" prefer the sound of the Burr-Brown implementation within the XMC-1. You might not, but that's okay too. The great thing is you do have the flexibility of trying it both ways and choosing what "you" like.
