thinking out loud.... "parts in the signal chain"

so, I was reading an old article recently, and I was wondering if any of you all had a similar thought process....

From an article published in June of 2007...

Originally Posted by article
First, to get the best possible sound from these expensive drivers one needs to match the woofers to the mids and the mids to the tweeters in as many specifications as possible to minimize parts needed to run them.

Especially with horns and single-ended or low wattage amps, passive crossovers and parts significantly detract from their sound, especially higher order crossovers.

Thus, for the main speakers I use VacuumState RTP-5 preamps that were built with 24dB active crossovers as part of the preamp's regular circuitry and Behringer 24dB active crossovers as the preamps for the other speakers.

Thus theoretically, no parts are in the circuit between the preamps and amp other than what would have to be there anyway. Only the tweeters have 1 capacitor on them for a 6dB crossover to the mid-horn.

so, to my way of thinking...
this thought the author had expressed, regarding limiting component counts for sound optimization, confuses me....

what difference does it make when a stage/circuit is integrated into a component or daisy chained as a discrete unit? you know, assuming the hook-up is proper and checked for correctness...
I can understand the concern when specifically thinking about low wattage, high efficiency rigs - I guess - due to network insertion losses, etc. -- but otherwise? Thoughts?

in the same vein, about how long are professional studio signal paths...
I would guess they are pretty significant...

generally - are there problems when the installation is thoughtful and well done...

I just thought I would share something I found interesting and amusing...

The paragraph you have included here is really about how speaker drivers and passive/active crossovers function.

Active has many benefits over a passive network.

If he is describing having the active x-over in the same box as opposed to separate then there's not much to be gained from that approach.
