I'm quite sure it decodes DSD across HDMI 1.4 without PCM conversion.

The 40.4, 50.4 & 70.4 also have 2 channel .dsf support .

"DSD Processing / Direct mode" checked on : yes, this is highly probable.

The Integra 70.x and 80.x, and their Onkyo equivalents, have been DSD capable for quite some time. Ditto for the top Denons. So, this is nothing new. I have this in my Integra DHC 80.2 prepro, but I never use it beyond a few comparative evaluations. It does not sound all that good to me,especially not in Mch where there is no distance compensation or bass management. But, even in stereo, it pales by comparison. Much ado about nothing, in my view. But, to each his or her own.

Having said that, I do prefer bitstreamed DSD into the Integra, then converting to PCM there for full DSP processing including Audyssey. Now, that is outstanding sound that in Mch brings me as close to live concert hall sound as virtually anything I have heard in many decades as an audiophile and concert attendee.

Agree with your last paragraph. I am not technical enough to explain why, but DSD bitstream for a receiver to decode ready for audyssey processing sounds better than converting to pcm in the player.

And for the money, this is the best way of getting accurate acoustic music.

It might well be player dependent. I use an Oppo 93, and a number of experiments with friends convince me that its internal DSD -PCM conversion can be bettered. Possibly, that is a function of conversion resolution: 88k in the Oppo vs. 176k in some other players. But, I have not been able to verify that.

It might also be the result of reduced jitter. DSD is typically transmitted as compressed data over HDMI, I believe, while converted PCM is uncompressed. There is some pretty good theory that says compressed data streams over HDMI are less prone to jitter. I also find that compressed Blu-ray codecs generally sound better than uncompressed LPCM after HDMI transmission, which may or may not support the concept.

Whatever. Many in other forums with different processrs agree with us that bitstreamed DSD sounds best, in spite of the conversion to PCM in the processor.

Happy listening.
