Hello braders
DTS HDMA at Dolby TrueHD, there are brands and models that support these formats. I am using a Mede8er MED600X3D and it does support both audio formats mentioned above.
As for Dolby Atmos and 4K, these are fairly new technologies in audio and video. In line with media players...I have a few questions as well...
1. Are there existing media files that have/are either/both Dolby Atmos and 4K?
2. Do you need a receiver that supports both Dolby Atmos and 4K?
If the answer to both questions are "yes," specially #2...di na ako mag upgarde ng media player!!! Magastos yan mga braders...hahaha!
