Note the wining sound in the background is the Sony SDDS D3000 it sounds actually lot quieter in the actual system, it's due to the headphone monitor on the D3000 and I could have pressed the SELECT button to reduce it, but I forgot. So this is the, Audio Surround Upmixer Matrix Conspiracy.


Everyone in the audio home cinema community thinks? Dolby atmos is great, or it is lousy with overhead surround. Most would switch on, "dts neural x, upixer". They then say it sounds better than Dolby atmos? Most have no proper way to monitoring the sound.

Auro3d is the worst upmixer between Dolby dsu and dts neural x. The channel dB crosstalk is horrendous the leakage. sounds like a cheap Tandy, Radio Shack, graphic equalizer with "stereo expand" from the 1980's.

It may also sound like stereo width that is a feature on the Behringer DEQ2496 to narrow the stereo down to mono or widen the stereo width even wider, when using the Auro3d matic "Strength" from 1 to 16. It just makes whatever is on the front L R sound not so good. In this day and age of digital audio. I prefer analogue seems to work fine, so does the analogue circuity on Voyager 1 and 2 even at 50 billion miles moving at a speed 47.000MPH per second, per second can still receive and transmit back that takes 24hrs.


It is better to add on external matrix decoders to extract centre phantom sound or additional stereo side surround rear surround from a PLIIx and just wire it into the existing system or use an Audio Mixer with the line-inputs and stereo outputs , oh can do many things that would be still a matrix expansion to the system only far better than what is being offered.


atmos, auro3d dtsx discrete is different just as dolby 5.1 7.1 4.0 4.1 is all discrete mix, stereo discrete with a mono centre phantom with instruments fixed or panned left to right or centre phantom.
