How are you getting your surround sound?

you have discrete multi-channel, plus object based multi-channel (Dolby Atmos type prscesses). they are different and need different tools to use.

then there are the media types.

--blue ray discs--Dolby Atmos
--4k blue ray discs----Dolby Atmos
--Roon/Tidal multi-channel music file streaming 
--Kaliedescape movie server
--streaming video; Netflix, Youtube, Amazon Prime, etc.

Ripped. I have no patience for previews, commercials and/or disc loading

I have a older high end surround processor, with excellent speakers and amp. We stream through Apple most of the time, also Amazon, and Comcast. For the last few years streaming has been sonically equivalent to blu-Rays. We bought a few 4K disks and stopped. We are now getting rid of our thousand + disks. Take up too much space, and provide no added value.

Thank you for the responses. I assume "ripped" means it's still coming from a disc and ripped onto your PC/Harddrive for storage.
@ghdprentice when you stream through Apple and Amazon, are you able to get your movies with 4K video and discrete Dolby Atmos surround sound?

@scar972

Movies that are available in 4K are streamed in 4K on Apple and Amazon. We watch 3 movies a week and virtually all are 4K. Both Apple and Amazon stream movies in ATMOS. Our older processor does not support ATMOS. It does support TrueHD and DTS… etc. and are indistinguishable from those played on our 4K OPPO.

Thanks for the information, I'll check out what's available on Amazon and Apple.

I use an appleTV, i used to use a NvidiaShieldTV wasnt happy. The Apple streams 4K HDR. I down convert to 1080p/HDR, the pic is jaw dropping and distracting Lol. I run an JVC RS400
      (native resolution 1080p). The pic is 100”x42”(2.35:2) AT screen

That sounds awesome! How are you getting your 4K movies on the AppleTV? Trying to determine if most people stream their movies now or still popping in a disc.

Via Apple TV device. Although when traveling I may use my iPad or MacBook connecting directly to HDMI Tv input. 
Is that your question?

I stream from Amazon and HBOMAX mostly, i use an HDFURY To convert down to 1080p but it passes the HDR to my PJ.
Apple decodes audio so ur processor/receiver will show multi ch in. Now On the other hand my Denon receiver shows Dolby Atmos, so I guess it pass’s  Dolby Atmos but not Dolby Digital 5.1

Generally for best quality (especially audio) you still need blu rays. There are some fancy specialty download services. But normal streaming from Amazon, Hulu, Netflix is pretty terrible. Apple and Disney are a little better but still way behind the blu ray.  

For surround, I use HDMI from an Ayre DX-5 DSD disc player to a Bryston SP3 processor. I suppose it would be trivial to add HDMI from an Apple or Amazon streamer. Only complication is that I take video straight for the DX-5 DSD to the projector, but Bryston claims to pass video through the SP3 without processing it. And if I do that, I might as well run HDMI from Cox cable through the SP3 as well. The SP3 returns balanced front LR to the Ayre preamp and sends side and rear surround to a pair of NAD amps.
