Hi Lou and fellow enthusiasts, I'd like to clear up a couple things, but for now I'm only talking about bi-wiring a loudspeaker. Bi-wiring is simply using 2 wires for a signal path, between two points where 1 wire would normally suffice. The debate, whether 2 is better than 1, I'm not discussing here now. Below I describe just one bi-wiring connection but there are a couple of others. If the amplifier has speaker terminals A & B than 1 two conductor wire can go from amp speaker terminal A to the single loudspeaker terminal & a 2nd 2 conductor wire from amp speaker terminal B to the same single loudspeaker terminal. If the amp has only 1 speaker terminal per channel than both 2 conductor wires are twisted together into the same terminal. That pair goes to a loudspeaker with 2 terminals and a jumper in between. The jumper is removed and 1 pair goes to the upper and one pair goes to the lower loudspeaker terminal. And then there's vice-versa. All these bi-wiring methods are electrically IDENTICAL. Amp terminals A or A & B are the same except the wires are "jumpered" and switched internally. Bi-wired loudspeakers with 2 terminals A & B are also the same except the wires are "jumpered" internally whether the stock strap jumper is there or not. Point being, bi-wiring has nothing to do with stereo amps. mono amps. dual mono amps, balanced amps, differential amps or bi-amping. Acid Jazz, Funk & Brass 🔈🔉🔊

Exactly, bi-wiring is about what happens inside a speaker and those interactions. Many have abandoned bi-wiring for a number of practical reasons as opposed to electrical ones. I try to address the practical problems where people really mess things up leading to manufacturers going single wire. Here's one for you: Internal Bi-wire cables vs shotgun. What's your take?

@@audibleeleganceinc . Exactly? Well then I guess what I'm asking then is, why the thumbnail is Using Mono Blocks vs. Two Stereo Amplifiers are you talking about bi-wiring? It's a different subject and has nothing to do with mono's or stereo's. Anything can be bi-wired including RCA cables, XLR, TRS, Power cables, HDMI cables and even optical cables. What's that got to do with amps & speakers? Just curious, in the spirit of opinion sharing.

@@TriAmpHiFi The option presented by stereo amplifier use is to have independent amplifiers on each of the bi-wire binding posts. 4 amplifiers as opposed to 2. The results will depend upon the speaker being driven and the quality of the amplifiers themselves. Electrically, the alleged benefits of bi-wiring is the avoidance of internal interference within the speaker itself. Where people really screw up is using differential amplifiers for bi-wiring like vacuum tube for the treble and solid state for the bass. Often times the input impedance and sensitivity are very different. That creates all sorts of havoc.

. To bi-wire a loudspeaker that has 1 pair of inputs with a stereo power amplifier having 1 pair of outputs for each channel requires 2 lengths of 2 conductor cable and having both pair of plugs share the respective outlets. This particular type of connection uses 1/2 of the stereo power amplifier's potential watts to one loudspeaker. Acid Jazz, Funk & Brass 🔈🔉🔊

. I'll add that the speaker level signal through both cables are in-phase with each other. The line level signal through the stereo power amplifier may have 2 or 4 internal signal paths depending on if the amp is differential or not.

Well, that's why Naim Audio under Julian Vereker went from a stereo amplifier NAP250 to 135s to the six pack of absolute delight.
