Ultimately I think it won't matter since I'm going to route all 2-channel audio through the Emotiva XSP-1 preamp rather than the receiver. So long as the HDMI DAC piece is good, I'm happy!<br /><br />I actually have 2 Emotiva XPA-1L'sArchimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-16372055236807597592013-10-28T15:47:33.552-07:002013-10-28T15:47:33.552-07:00Good to know that the Onkyo hold up as a good DAC ...Good to know that the Onkyo hold up as a good DAC & Pre Amp in "Pure Audio" mode ... but bad things happened when you turned on the video processing in your last post! Were you able to solve the ground loops issues? My NR901 is an older model but has a two prong power cord (hot, neutral) - perhaps to eliminate ground loop issues. <br /><br />Thanks for another informative write Anonymoushttps://www.blogger.com/profile/09264934946606076039noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-91981267541200776632013-10-28T13:45:45.890-07:002013-10-28T13:45:45.890-07:00I believe the signal path must be different and be...I believe the signal path must be different and better shielded from noise coming out of the DAC than the full analogue pathway. Perhaps a way to check this out would be to look at the noise level difference between the front RCA input vs. the rear.<br /><br />Since analogue isn't as important as digital input for me, I'm just glad the HDMI input seems clean.<br /><br />I guess one could Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-49243498631092931172013-10-28T13:07:37.664-07:002013-10-28T13:07:37.664-07:00Yes.

Your NR809 uses the same main DAC chip (PCM1690) with essentially the same feature set and topology so it should sound essentially identical.<br /><br />Enjoy!<br />Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-1595213444661493812013-10-28T05:51:36.442-07:002013-10-28T05:51:36.442-07:00Thanks again.

My assumption was that the signal path in the HDMI test would be near-identical with the exception of the addition of a DAC stage and I'm still not sure why this isn't the case. Can anyone educate meLazyhttps://www.blogger.com/profile/02503710911882514850noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-47077231460058604412013-10-27T17:52:23.674-07:002013-10-27T17:52:23.674-07:00Thanks for sharing!

I fancy I can hear a *slight* difference running direct via HDMI (i.e., using the Onkyo internal DAC, which is capable up to 24/192) and running analog in through a low-end external DAC (e.g., Dragonfly or Meridian Explorer), but no way I'd pass a DBT on it ;)<br /><br />As you say, pretty good performance from these AV receivers these days.jhwalkerhttps://www.blogger.com/profile/14734724684407804183noreply@blogger.com
