While I don't have one, the unit has been reviewed in great detail on the Stereophile website: http://www.stereophile.com/content/sony-hap-z1es-high-resolution-file-player#dV2zEVQZoZQK5BCl.97
I believe this article should cover any questions you might have about the unit. please get back to me after you read it and let me know if the review helps.
