Isn't two speakers with BACCH XTC the ideal configuration though? Whether with actual speakers or simulated via headphones. Would adding more speakers (virtual or real) add anything positive to the sound quality?
I'm not sure this is true... SINAD per frequency per power should tell the whole story, I think. Please correct me if I'm wrong.

Something has occured to me. We have smartphones, smart cars, smart fridges and what do I know, perhaps even smart toilets. But why don't we have smart headphones? Couldn't it be possible to have a smart headphone which would eliminate distortion by playing an inverted signal, a principle...
Headphones have very poor SINAD. Even the best measuring ones have around 0.1% THD+N, which is 60 dB SINAD.
A concrete example. Let's take the Stax SR-009, with ~0.1% THD+N.

This appears to have a stepped attenuator for volume control? Channel balance would appear to be the one last thing the Benchmark HPA4 has on the Topping A90. Could this SMSL be the ultimate amp? Is Amir going to test it?
Thank you very much for your detailed answers. One more thing that interests me is what headphone in particular would you recommend for optimal speakers emulation. I know the HD800 is widely used for 3D audio, and Stax models are held in high regard too (also by Smyth Research). In your...
I just realized something. As far as I know, the only sources indicating that some headphones have greater resolution / detail retrieval than others are subjective reviews. Oftentimes from the same people who would have you believe in benefits of multi-thousand $ cables, 192+ kHz audio and other...
I think I understand now. You need your own personal HRTF for the BACCH-hp to work optimally.
Do you thing something like this https://www.genelec.com/aural-id
could work too at the highest level? You mentioned that the BACCH VLS is not foolproof. However, if I loaded my personal accurate HRTF...
