Potentially ... but maybe inaudible ..
You would be removing a connector from the signal path so simpler cleaner path .. which generally results in cleaner clearer sound ..
I've certainly read a lot of comments about the improvements gained from using certain connectors, and I've experienced clearly audible gains in clarity when I removed some unnecessary banana plugs from the speaker cables.
Makes sense ... the connector is part of the path... as are all of the the signal traces, and all of the components in the amp.
And amps with carefully chosen components and construction are certainly the finer sounding amps..
It's maybe an iffy thing tho ..
Active speakers are set up as you describe, but as far as I know, there is no clear consistent clarity advantage to active v.s. passive speakers ..
It's essentially an audibility phenomenon ..
..
If, as you state, connectors are a factor, then wouldn't adding second set of connectors at the speaker, as necessary for biwiring, create an additional potentially negative factor?
At some point, unless one is driving a single full-range driver per channel, the signal must be divided into driver-optimized frequency bands. That division has to be accomplished by either passive components (inductors, capacitors, and resistors) or active powered circuitry. That, obviously, takes place either inside a speaker via an internal passive crossover network, externally between pre- and power amps via an external active crossover, or in some exotic cases internally in a powered speaker (although I believe in most cases the crossover networks in many powered speakers are still passive, functioning after an internal power amp). Regardless of where those networks are located, those components will have many orders of magnitude more imprint on the sound than straight wire. Reference the oft-touted goal of constructing preamps that are simply "straight-wires with gain."
IF biwiring offers a significant sonic advantage, as described by the link in the second post in this thread, by allowing different frequencies to optimally transmit through each of the two biwire paths to the speaker, then would it not follow that active powered speakers would have a SIGNIFICANT advantage over passive, in that the signal path between the amplifier(s) internal in the speaker to the XO network and/or drivers themselves would be so much shorter than standard speaker wire runs? And yet... as you say.. that has not been demonstrated to be the case.
I have a pair of Magnepan 3.6R speakers biwired to a Van Alstine Transcendence III amp, mostly because I had some extra wire and connectors on hand and figured what the heck. I would LOVE to empirically (or as empirically as possible) test the audibility of differences attained by bi-wiring. On the surface, it seems like it should be an easy thing to do; combine the biwires on one side so that the resultant summed wire gauge on both channels is the same, play a mono signal, and compare what I hear. The catch is... room placement. There's virtually no way to put the speakers in exactly the same spot, and the influence on sound due to placement is so much greater than any possible influence due to changing the electrically-identical location of connection to the internal (external on these speakers) passive crossover as to render the test pretty much useless, unfortunately.
If one hears a difference, one hears a difference. If one does not, or has not yet read or heard a cogent explanation for the existence of improvement attained by biwiring, then one is branded as either owning an inferior system or simply not having ears good enough to hear the difference.
I truly DO wish I could both design a perfect test that removes all other variables and allows me to A/B/X biwiring vs same total gauge and composition wiring, and find an article that unequivocally, based on accepted physical and electrical engineering theory, explains why biwiring is better. I have searched for years... I do find it an interesting subject. Still searching.
EDIT/ADDITION: I'm honestly not trying to be argumentative; I just went back and re-read the entire aforementioned linked article, hoping to find something that further elucidates physical causes for improvements hear by some when biwiring . There's a few instances of misapplication of logic in the "layman's" description of what is happening within the truck-and-motorcycle traffic within the wire, ... for instance...
"Charges do not flow round the circuit one at a time; rather they behave like a nose-to-tail traffic jam on the motorway."
Followed, a few sentences later, by...
"Once the circuit is made all the traffic starts to flow out of the red terminal of the amplifier using the single speaker cable, into the red terminal of the loudspeaker where they get separated by the crossover, do the work in their respective loudspeakers and then join back up at the black terminal of the loudspeaker and use the single speaker cable again to reach their ultimate goal – the black amplifier terminal! "
and....
"Also there is no waiting for the first charge to make it all the way around – it’s a permanent traffic jam remember? As soon as the green light is given traffic is already flowing at the black amplifier terminal."
I mean, yes, I get that they're trying to explain very simply how current doesn't flow through a wire in a stream like water through a pipe, without delving into the physics of it too deeply (charges going from negative to positive, but the "holes" going from positive to negative, skin effect and speed of transmission as a function of frequency, etc), but still.... they seem to be basing a lot of their "proof" upon some substantially incorrect similes,but they at least admit that it's not exactly a correct analogy.
The part that gets me is the charts in figures 4, 5, 6, and 7. They tout the improvements in intermodulation distortion provided by biwiring shown in the charts for the separate woofer and tweeter runs, comparing it to the total intermodulation distortion shown in the single run. YET... they neglect the fact that the distortion present in the two biwire runs SUM anyway upon listening to the total output of the speaker... and looking at the chart closely, that sum of the separate biwire intermodulation distortions is pretty much identical to the plot of the intermodulation distortion of the single run.
Yes?
This was all over a year ago. System sounds great, but always has. Really, the only way to TRULY know if there is more going on here, at least for me personally, is to be able to remove every variable OTHER than the wire, but I can't think of a way to co-locate two Maggies playing the same mono source.
