Do NOT Blow Your Entire Budget on Two Channel Audio

And if you got no space for a system in your house, there is always your car:

Surround sound (home theater ) is not exactly the same as 3-D soundfield as in Choueiri BACCH filters ...

For those who want to read the basic in a short text :

This citation comes from a user of BACCH in ASR forum :

«“BACCH is focused on stereo and getting the most out of stereo. We have two ears only and we therefore, in principle, need only two channels to get the cues needed to correctly locate sound in 3D. This is the binaural approach (as opposed to object-based Surround Sound approach) to 3D sound.

Multi-channel Surround Sound (i.e. Dolby 5.1, 7.1, Atmos, Auro3D, etc.), wether channel or object based, is not of interest to us. It is not a focus of research and development at Theoretica (nor is it a topic of academic research in spatial audio, where the main three approaches are: binaural, higher-order-ambisonics, and wavefield synthesis).»

BACCH is wonderful from what I heard from others. I have not heard it myself. Too hard to do. I don’t want a Mac and it seems a bit too customer. Edgar comes over and does install and super expensive. I will wait for the BACCH in a box for less than 5k. Then I will jump in. The bonus of that kind of system is any 2 ch music to feed it. Atmos or object based has to be mixed and will always be limited. 
 

For the poster that says their tuned 2 channel system is just as good as a 5.1 has not listened to a proper system. Also atmos is min 5.1.2. Just adding a center for dialog improves movies.  2 vs multi ch for movies no contest. Playing a 2 ch song via some stupid DSP to multi ch surround. Yuch. Just have a good 2 ch setup is better.

I think the bigger point is you can have both. As long as your pre has bypass.  If it does not then you will end up compromising the 2 ch system to share speakers and amps.  

Comparing Quad from 70’s is not exactly even close comparison to object based music. 

Streaming also has opened the door to make this generation of multi channel music to be more successful. Comparing to SACD and DVDA is unfair. Need special players and setups etc.  not to mention to finding the discs. Millions upon millions have apple and Amazon and tidal. It’s there ready and waiting. The entire library of them. 

this forum is not exactly know for its open mind-ness and probably not the best place for the OP to try and find others to join in the fun. 

@mahgister Thanks for the information on the Bacch filter. Just watched a few interesting videos on the technology and the product. I believe you may be correct Mahgister, depending on what they can get the price of the unit down to when in full production it looks like it could make Dolby Atmos the new MQA.

BACCH has really dominated the market in the 8 years it has existed. Totally dominant. Probably at least a few hundred people have heard of it.

It is a good technology for one person, calibrated for that one person, in one specific environment. No listening parties. No trade shows with more than one person in a room. No listening with your spouse, family or friends. That limited market means it will always be a fringe product and hard to justify for any content creators.

If I were them I would ditch their present business model and work on only the ear calibration for headphones. Way bigger market. Stupid to compete with ATMOS and similar. They won’t just lose. They already lost. Ship has sailed. Integrate with them and make them better for the headphone crowd.

@fittebd you think most music available will work? Heck no. It would all need to be remixed. Who is going to do that for such a small market? Almost no one. The only steady stream of music that could be adapted automatically would be ATMOS.
