So these are individual files and not disc rips? Are they MKV or AVI? The container really shouldn't matter since, as you said, all players are playing the same audio stream.Except in the case of DTS
. DTS is a layered audio format - It starts with DTS-core, it can then have an optional DTS-HD stream layered on top of it, and then another optional DTS-MA stream layered on top of that. So if you have a DTS-HD stream, a player may chose to play DTS-core or DTS-HD, depending on many factors. The most common factor is the license the manufacturer paid for. Other factors include the medium (only DTS-core can fit down S/PDIF) and the EDID data from the AVR (if using HDMI).
I also play a Audio 96/24 files and you can tell in 5 seconds on those files as well
Are those audio files? If so, they would probably come out as PCM or AAC, as the concept of bitstreaming doesn't quite fit. If they are AAC, like iTunes music would be, then they might be decoded in the player or passed on to the AVR. Again, the AVR should be able to tell you. Are they compressed? what is the file format?
there is no way 1 is selecting bitstream and the other is not; there is ONLY 1 audio track on the files I am playing. . .
But that has nothing to do with it. Although there is only one audio track, one player might decide to bitstream that track, while another decides to decode the track, and a third might decide to decode and downsample the track. Downsampling from 5.1 to 2.0 is very common when the manufacturer has scrimped on the licenses.
. . . the ONLY setting on my HDX that I use is Bitsteam and the ONLY setting you can use on the Realtek players I used is RAW on the Egreat or RAW or Auto on the iconbit so that is nonsense. There is also a setting for HD Audio that is set to on on the Iconbit
What you set it for is not always what you get. Even though you set it for bitstreaming, it won't bitstream if the license doesn't allow it. I set my NeoTV to bitstream all formats, but it almost never does because the HDMI EDID data says it isn't supported (although that is clearly not the issue you have). Again, the AVR would tell you.
the Receiver/Pre Amp was showing either DTS HD , or Multi PCM so that is NOT the issue
OK. This is the type of information we need. If the same track shows the same DTS HD on all players, then they are all bitstreaming. Multi-PCM would be normal for surround-sound music, but would typically indicate that the player was decoding and not bitstreaming. Video with native multi-PCM tracks do exist, but they are rare these days, as they are just too stompin' big.
. . . and how do you explain that many others have compared Sigma and Realtek and thought the Sigma looked and sounded better; that was not me posting but other people
There IS a difference in the sound between my HDX with Sigma
Please, don't misunderstand. I totally believe what you and others are hearing. I'm not questioning that at all. Something is clearly different between Realtek and Sigma, and I'm just trying to determine what it is.
the Realtek chip has to be doing something to the signal before sending it to the Receiver that degrades the sound ; I know my receiver is not doing it
Absolutely. And I suspect we can eventually find out what it is. Just bear with me . . .
