Why HiFi manufacturers don't make active crossovers anymore?

but there are usually some trade offs, like 3x more amplifier channels, and a lot more parts that go between the singal and the driver.

Audiophiles are generally happy to spend quite a lot of money on their equipment. Why would you be reluctant to spend a bit of money on another amp to obtain the benefits of going active, when youre happy to spend thousands on other things like cables and accessories which bring little or no benefits?

There are less not more parts between the amp and driver with active. Less expensive capacitors and inductors. 

If using DSP with analog sources, I presume that the signal is converted to digital right? 

So phono signal for example will be digitalized and converted to analog again....  I think this is the main reason why I'm reluctant in consider DSP if choose to go through the active cross over route...

I’m seriously considering this, instead of build the passive cross over for my speaker project...

This multi channel amp and active crossover, would like to know more about if this example can be a more easy solution to divide the frequencies for the speaker’s drivers, instead of build the passive crossover for the woofer, radial horn, and super horn tweeter, as is suggested on the Fostex speaker’s plan.

More, easy, straight forward configuration, but more expensive for sure... well this amp, preamp and active crossover from Accuphase I found some to sell occasionally on the web, sometimes the preamp and the active crossover appears at a more reasonable price in Japan I think..

Anyway, what do you think about this solution for a 3 way loudspeakers?

I noticed that on the PX-600 brochure, Accuphase shows a picture example with this devices used with 3 way speakers system, with the exactly same design of the ones that I will start to build, take a look... maybe this says something? probably a good match?

All components are from 2001, then, they are soooo vintage to worries about repair, recap, and etc, if considering very well cared units, the F25 is from late 90’s but was re-released in 2005.

Let me know your thoughts about, very interesting stuff....

yes, 3 way with active 3 way crossover and 3  separate amp is step up, but is not for commercial market , not too many customers  gonna buy, and don't make sense put it production, Meridian make this with build in 3 way active crossover and  build in  3 class D amps.  is very costly, and some folks don't like class D, My company Bache get experience to make what  looking for, so only small company can realize you protect

That's why I'm thinking about the option that I posted above, maybe you can cut costs with some "more vintage" components, and a multi channel high end amp...
