The device is violating the HDCP agreement that comes with HDMI interface unless it forces the sample rate to be at 48 kHz or below.- Home Theaters: use a BluRay player output in hdmi, then use a converter from hdmi to multi ch AES/EBU, then finally from that converter to Okto DAC8 AES/EBU inputs. The only such converter I found is Arvus (http://www.arvus.io/hdmi-2a.html ).
This Arvus converter seems to be quite expensive.
That said, I think it's important to note that most of the differences between good DAC's (and I think all of the DAC's measured here) is very, very subtle even if, as I and some others believe, it can actually be heard.
Is that part of the agreement valid in all jurisdictions? Region coding was part of the agreement with DVD, but New Zealand ruled it an unlawful restriction IIRC, so players there had to play content from any region.The device is violating the HDCP agreement that comes with HDMI interface unless it forces the sample rate to be at 48 kHz or below.
It already does and has for years.once the standard includes passing Mch PCM at 24bit/192kHz then it will be truly useful.
VanityHD-cards for Oppo-players.
I have Vanity103HD in my Oppo BDP-103, outputing 7.1 in AES3. Works flawlessely.
Now I'm confused. Amir says HDMI has to down-sample to 48kHz, so how can it also be passing 24/192 Mch.?
I guess I'm really out of touch: Nowadays can HDMI pass Mch DSD to a DSD DAC with no pre-conversion to PCM?
But, in theory, if I was to back-up my BDs to a NAS and play them from there through an AV receiver connected via analogue outs and the software player said it was playing 24/192 Mch would the receiver still deprecate the resolution?
I do not know what Amir said but I can confirm that I do this all the time without issue. Could be dependent on specific hardware but it is not a problem for HDMI.Now I'm confused. Amir says HDMI has to down-sample to 48kHz, so how can it also be passing 24/192 Mch.?
Depends. I can do this from my Oppo players but not from my servers.I guess I'm really out of touch: Nowadays can HDMI pass Mch DSD to a DSD DAC with no pre-conversion to PCM?

See my other posts. This is possible but it depends on the specific hardware devices.HDMI can pass high resolution audio to another device, but that other device can not output high rez digital due to contractual agreements, not due to physical limitations.
All that is irrelevant.This is similar to the ANALOG SUNSET license agreement.
"... After December 31, 2013, Blu-ray Disc players with component video output jacks will no longer be sold. NOTE: To comply with this license agreement, Blu-ray Disc players by Sony manufactured from the beginning of 2011 only output 480i resolution through component video. ..."
The agreement was created by Intel so I imagine their lawyers have considered enforceability in a bunch of jurisdictions.Is that part of the agreement valid in all jurisdictions?
I think some are inferring more from your statement than they should.The agreement was created by Intel so I imagine their lawyers have considered enforceability in a bunch of jurisdictions.
To be clear, the restriction applies to any digital connection that is without approved copy protection technology. AES/EBU has no copy protection so restriction must be enforced. This restriction comes from the HDCP component of HDMI protocol:Now I'm confused. Amir says HDMI has to down-sample to 48kHz, so how can it also be passing 24/192 Mch.?
I think so too. To be very clear, you can send any resolution audio over HDMI and a device can play it. The restrictions are only there if you try to retransmit the audio format over another digital connection without copy protection. HDMI by itself is fine as is a DAC, AVR or processor that receives HDMI and plays that format in analog.I think some are inferring more from your statement than they should.
