Phantom II Custom 5.0 surround system experience and suggestions

[ogs]

Thanks for this very informative post! The Custom is indeed an interesting model. I didn't know that latency is zero on the Custom. Most interesting! I have seriously looked at getting a pair of black Customs (I'm not into MCH). I'd use AES/EBU for signal transfer, possibly driven by a Mutec MC-3 +USB. Dante is of course an option, but as a Roon user a virtual sound card might not be the best.
Does the Custom have any "quirks" (other than the signal level setting you describe) worth mentioning?
