4K/UHD bluray players that decode DTS to Dolby?

With 4K bluray players starting to emerge now, seems we really need to start keeping straight which ones will allow those of us with Sonos Playbars enjoy some semblance of Dolby sound when certain 4K blurays only offer DTS. (Note, I haven't yet purchased a 4K bluray, so am unaware of the typical sound offerings.)

But we went through this once already, for regular bluray players, with many threads devoted to outlining the multiple Samsung models of bluray that decode DTS to Dolby 5.1 (I ended up buying a Sony that also does so). Now let's do the same for 4K players.

So far we have the Samsung UBD K8500 (which seems to clearly decode DTS to dolby.) Now what about the Philips? The Panasonic? The Xbox One S?

Anyone have any idea?

Hi Tom, No i haven't had chance to listen to the Bose Soundtouch system yet but am hoping to get proper demo in my local Bose store in the next week. After my Yamaha experience I wasn't intending any more demos but your response has got me intrigued, so i'll give it a go and see what i find? Just out of interest - what setting do you prefer for movies - Trueplay On or Off??
Sony KD-XR65A80j, Panasonic Ubd9000 (discs), Samsung UBD-M9500 (media files) , Sonos Arc, Sub (gen 2) , 2 x Era 100's, 4 x Play 1's, 1 x Move

I use Trueplay enabled. Though, since I'm an Android user I was disappointed that Sonos wasn't supporting that OS. In fact none of my friends or family use an apple device that I could borrow. So, I went on ebay and bought an old iPhone 4s for $25. After setting up Trueplay the sound was noticeably improved. It had a fuller and more balanced sound.

Message to all - Just seen on Highdefdigest that Samsung have announced the launch date of the new M9500 - April (US) - so hopefully pretty soon after for the UK.

I've all but given up hope on a DV HDR option for 2017, looks like the first 2017 HDR UHD Bluray player that transcodes DTS to DD on the fly will get my business and i'll have to live with no DV HDR on physical discs when they come out thanks to the dreaded Sonos limitation. But hey-- everyone streams anyway though right?

Message to all - Just seen on Highdefdigest that Samsung have announced the launch date of the new M9500 - April (US) - so hopefully pretty soon after for the UK. Noticed that article too. Very informative about pointing out what new UHD bluray players are forthcoming. The tricky thing is, of all of them, it seems that this Samsung M9500 is our best (and maybe only) shot at the Dolby transcoding feature. There are three new ones from Panasonic - but if the top model that's out now doesn't have the feature, why would those? A new one from Oppo - again, seems they never include that feature. A new one from Philiips - doubt it will have it if the current does not. Of course, the LG is still on the way - but I continue to have my doubts there (no previous LG players have had that feature based on my research.)

So we're down to the new Samsung.

Why must it be SO difficult???

There's still a small sliver of hope that the new Xbox (Project Scorpio) might double as a decent UHD blu-ray player that can handle HDR10 and DV through a firmware update. Considering all consoles in the past have been able to transcode DTS to DD 5.1 over optical via bitstream-- that could end up being a real option. All this assuming that the picture quality doesn't suck.

Sounds dumb but, I feel like there's an opportunity for Sonos to reach out to one of these suppliers (like Oppo) to see if they can include DTS to Dolby 5.1 transcoding in either their current models through firmware update or in a future step-up model.

I'm just so fed up with having to even deal with this for a $2000 surround system and being told its not a limitation because people don't buy blu-rays anymore... because they do, especially those who plunk down $2000 for a home theatre audio setup.

Any idea when the new XBox is projected to release? Love the idea of Sonos reaching out to a brand with that request. I'm just not sure that they would give Sonos the time of day. Would take big $? Or could the brand be convinced that enough of their audience are also Sonos - and potential Sonos - customers, such that it's also in the brand's best interest. I also have no idea how big of a deal it is to add this (seemingly simple) feature in audio settings.

Only indication for the new Xbox is "holiday season 2017".

I'm willing to wait a bit to see what to get. Might pick up the old samsung on the cheap just to tide me over with HDR10 till something better comes along.

Yeah, I am also considering buying a Samsung K8500 to get by until a better model comes along - be it the M9500 or the LG UP970, or ??.
I don't know anything about a new Xbox coming out. I understood that the current Xbox One S did support transcoding to DD5.1. Granted it only supports HDR10 at this time. But, since Dolby Announced they would have a software only version of DV, I thought that it was conceivable that the current Xbox could get an upgrade for this. After all MS announced that Atmos was coming to the Xbox in a future upgrade. Am I missing something with the Xbox?

.... when i got the guy to play some music 'Dire Straits - Brothers in Arms' i was shocked. They have no real musicality and sound horrendously bright, especially the 2700, I was expecting so much more! Even playing around with the DSP controls didn't help.... the piece de resistance - played the same Dire Straits and it was on a different planet - superbly musical, great top end and mid range all underpinned by the Sub, just a fantastic sound.

My hat is off to you for choosing one of the most musical and expertly produced rock albums of the past 30 years to use as your test disc. I prefer to test with that one, Peter Gabriel's 'So', or Robert Plant's "Pictures at Eleven". All three are flawless and bound to expose cracks in any system. They are also albums I'll listen to all the way through and enjoy, unlike most of the jazz stuff I've used for location tests and demos.

With that out of the way, did you get a chance to play some music that wasn't as well done? I've found that certain music that sounded good on my very neutral two channel system sounded compressed and even lifeless on the Sonos. A large portion of my music is FLAC/ALAC originals and remasters of sixties and seventies music, and most of it sounds very dead through my Sonos system. The newer, the better. Have you experienced this?
