DTS-X demuxing preferred file extension?

[Encore]

Hello guys,
I have been ripping and remuxing UHD-BDs for backing up and now almost running out of HDD spaces and not wanting to purchase more. I decided to encode my remuxes. Many of these have dts-x.7.1 audios. Unlike TrueHD audio (.thd) dts audios have three extensions (.dts, .dtsma and .dtshd ). My question is, what is the appropriate extension to use when demuxing dts-x.7.1 audio to preserve the height channel data?

Below is one of .dts audio file I did from a dts-x remux.

Audio
Format : DTS XLL X
Format/Info : Digital Theater Systems
Commercial name : DTS-HD MA + DTS:X
Bit rate mode : Variable
Channel(s) : 8 channels
Channel layout : C L R LFE Lb Rb Lss Rss Objects
Sampling rate : 48.0 kHz
Frame rate : 93.750 FPS (512 SPF)
Bit depth : 16 bits
Compression mode : Lossless

You can use any extension without problems (I use always .dts) because all audio software read the header to know the properties no mather the file extension.

Thanks tebasuna51. I have demuxed using .dts and .dtshd and media info show same details. But, I haven't had proper testing in my HT to see any difference. As, I want to delete remuxes, I thought of asking.
