"Active is not about where the amplifier is, it’s about where the crossover is."
IMO the speaker setup in your room is free and the proper specs to follow are available for free. You just need to take a half a day to move stuff around. What knee caps a HT once you get the room right isn’t the source or the processor, it’s the power. Did you ever wonder why a company will sell a 2 channel amp for more money than a 5,7, or 11 channel amp?
How can a traditional power supply provide the equivalent SQ to MCH amps as a 2 channel amp? This is like putting a 4 cylinder engine in a Lamborghini IMO. Whether you use a receiver or separates your speakers are still knee capped. To light them up proper those speakers would need to be bi-amped with proper power. Good luck fitting 22 channels of amplification for a 7.1.4 system into your room.
Now, enter the elegant and dare I say BETTER solution. Unhobble those wobbly knee caps and add rocket thrusters like I did with active speakers in the HT. Free up space, free up budget, add a frigging lightning bolt of power and get out of the way :).
