Your statement is far to general to be anywhere near true.

The way I see it, the preference for the passive crossover is another one of those folk-superstitions that account for 90% of the audiophile industry. I can understand where it comes from: the physical form of a purely active system in no way resembles a musical instrument so how can it sound musical? Even worse, digital audio is just numbers and bits, that, at heart produce a stepped output that simply must sound "grainy"; it stands to reason. By using old fashioned coils, glowing vacuum tubes and animal-based glue, we can restore the audio to its natural state; it stands to reason. The beauty of the passive crossover is that it is able to purify the signal at the actual output of the amplifier, so even solid state amplifiers with their plastic output devices can be purged of their inevitable plastic sound with some good old fashioned components glued down using techniques familiar to musical instrument makers.

But it's not easy to enter the guild of crossover designers; to a normal person the passive crossover may just look like a very small selection of components that can't possibly produce an optimal design, but this is where the long apprenticeship pays off. It turns out that there is a permutation of two or three components that always produces the optimum filters for any selection of drive units. It sounds unbelievable, but it's true, and the good crossover designer can find it.

Truly they are the Stradivarii of our age.

Cool! I have to admit, If I had that talent, I would never give it up for active. Why? Because..

It was funny, because it really captured the "logic" (or lack thereof) of the majority of audiophiles....

But hey, vinyl is made of plastic! Why doesn't it sound artificial? Or maybe its organic vinyl of some kind, what do I know.....
