What a ridiculous proposal. Almost no one has the room or money to implement your idea, even if they wanted to; and that's a big IF. Besides that, you already made this pitch in another thread. You need to understand that not everyone needs or wants "immersive audio".
Do NOT Blow Your Entire Budget on Two Channel Audio
Yes, two channel audio is here, and is not going away. However, object based audio is delightful, widely available on Tidal and Apple Music, and should be in the listening room of every music lover on the planet, not just "audiophiles. If you plan to be a music fan a year from now start building your object based audio system today. You will need:
1) A receiver/processor capable of Dolby Atmos.
2) A subscription to Tidal or Apple music.
3) A Firestick, ATV, or Nvidia Shield.
4) A minimum of 7 timber matched speakers and a subwoofer.
Once you experienced stereo would you ever go back to only mono? No, you would build a system capable of either mono or stereo. Now that object based audio has arrived do the same thing. Build a system capable of mono, stereo, AND object based audio. When Elton John heard Rocket Man in an object based format for the first time why did he demand to convert his entire catalog to Atmos? If you don’t know, then you need to go listen to Rocket Man in a good Atmos setup ASAP.
So, take your budget, DIVERSIFY, and get a good Atmos capable receiver or processor. Object based audio is NOT last decades surround sound or home theater. It is for MUSIC first, if you need a recommendation on how to allocate your budget feel free to post a question. Most importantly, you don’t NEED two systems, one for music and one for movies. A good object based audio system can play two channel music just fine. A two channel system on the other hand can’t play object based audio without a proper processor or receiver.
