I would say the chief differences between simple time-alignment and phase alignment is the frequency dependent component.

Simple time alignment (delay) electrically compensates for a physical displacement (HF driver is physically behind an LF driver, one can delay the LF signals so they are emanating from the speaker system at the same time as the HF signals so it is a unified front.

Sorry for the late reaction, I had a busy few weeks running up to the end of the year. But thanks for pointing out what is being meant with 'Phase Response Alignment'. So I was correct in the initial assumption that it's time alignment based on the frequency component. Which makes sense, but in my opinion should get a more descriptive name.

But... Interestingly, this is a feature that's also supported by Dirac Live, which comes with every AP20 and AP25. (And if I remember correctly also with more recent releases Audyssey, but which is limited to the home cinema domain). While I think that the auto-calibration features of the AP20 are OK, they're far from being perfect. So, it would be great to see or rather hear the difference between a Trinnov Ovation and Datasat AP20/AP25 in this regards.

Hi Marcel, Paris is not so far if you want to connect in our office sometime for a demo and q&a, I can probably ask the CEO to lunch with us. He knows the technology and development history, as well as being able to decide how much is able to be discussed vs proprietary.

Challenge accepted, if I'm in the neighborhood and the French aren't on national strike, effectively disabling any kind of transportation option, I'll drop you a line.

The bottle of absinthe will make a good companion to the mandatory alcohol test you're supposed to have in your car.

You don't need to worry about that. The mandatory breathalyzers only detect English gin, Scotch whisky, Belgian beer, Graanjenever, Schnapps, Chianti and Rioja. They cannot detect the presence of Claret, Armagnac, Kronenbourg, Absinthe, Cointreau, or any other domestically produced alcoholic beverage in a breath sample. This is a concession that the agricultural workers' union extracted from the government in exchange for refraining from dragging M. Macron to the guillotine by the towbar of a Citroën Deux Cheveaux.

That's great to know. I had a "guaranteed certified set" of them, they even were pretty hard to get around here... "What? Throw-away breathalyzers? Ils sont fous ces Français!"

So, I finally got a set, only to discover that they come with an expiration date... Now I bought like a 10-pack for about the same I paid for just one from AliExpress... I'm wondering though if they're correctly calibrated to avoid the detection of French alcoholic produce though.
