Reactor vs. Akoya

[extenso]

Checked with Cabasse - the room calibration works only for 15Hz up to 200Hz.

Regarding delay, I am copying the answer:
For now, 300ms is the minimum you can set because it's the time needed for the sound to go from the inputs to the DSP and the amplifiers. This buffer is necessary to allows a stereo pair to be in sync, in the case of the most efficient network. If you encounter some stereo stage or phase shift problems, you can increase this buffer in order the let more time for the synchronization between the products. It goes next through the audio processing for another 100ms. This time is set because of our patented high-quality processing algorithms (equalization, compression,...). It can't be reduced without compromising the sound quality.
So, for now, the minimal throughout time is about 300ms.

We are currently actively working on a way to a have a "direct" communication between the Aux inputs (Optical - RCA) and the DSP without the sync stage, so its latency could be reduced to only roughly the 100ms needed for processing. This also means that the inputted signal should be separated beforehand when using a pair (no stereo-streaming possible).
This option should be available quite soon but given it's still in development and need to go through all the firmware tests, it could take some weeks before public releasing.

Thank you, most helpful. This dampens my enthusiasm for TV use. 300ms seems to be too much. Confusing with the 200ms choice in the app, though. If only my local dealer would connect a stereo pair to a TV, but they always demo speakers as a traditional hi-fi setup. It isn’t 2020 yet in that store.
