Worked up? Oh not at all. I care every thing that means anything in this sport, and this doesn’t. These setups where the wire at the lengths being discussed makes no audiable difference one way or the other. However, to go through this act with the express purpose of having three foot long speaker wires makes no electrical engineering sense whatsoever. Bill Great, you said that, do you have to now be condescending and call people blockheads? Oh goodness no! (Sir) No name calling here....I would not do such things....just think my thread title is better! We simply agree to disagree ok?

That’s AWESOME! I had to blow it up to get a closer look 👀! Bill

I can only relate my experiences and comparisons, real world in my house, with my gear, listening with my ears. Comparing in stereo 2.1 listening; At various times an XPA-2, XPA-3, XPA-5 using 1 metre RCA interconnects and 6 metre speaker cables. To A pair of XPA-1L’s using 5 metre XLR interconnects and 1 metre speaker cables. In the latter set up, all of the gear is fully balanced/differential/discrete from the ERC-3 source, through the XSP-1 to the XPA-1L’s. Which is simply not possible with the previous set up because the monoblock power amps are internally quad differential and the other power amps are not. They guarantee no internal cross talk between channels by their singular isolated solution, whereas the other power amps share power supplies and live in the same box. They can be located close by their respective speaker and the other power amps can not. They make full use of the balanced circuitry all the way from the source to the speaker outlets, which the other power amps can not. Obviously in my case the short length speaker cables are just 1 part of a complete set up that has both a total absence of noise and sounds better in my room with my ears listening, ........a rhetorical question, asked I! And answered equally rhetorically Cheers Gary

Well, I passive vertical bi-amp my speakers with XPA-2s. Each amp sitting in front of each speaker with two and a half foot speaker cables. I have been informed by the President of the super secret "Monoblock Society" that that set up does not qualify as "mono-blocks". So there is that. Horse hockey - One amp chassis per speaker = MONOBLOCKS! I've done the same with one channel driving the bass, the other the treble. Yes, I COULD have run the amps in mono mode, reducing their impedance tolerance and increasing their distortion, but why? Mono is where you find it. Now having seven channels on one chassis may be one amp per speaker, but it AIN'T mono-blocks. But if you had a 7-way speaker with each of those amplifier channels running one driver of the speaker, then yes - that 7-channel amp would be a mono-block!

I've worked in theatres and other venues that take me a full day to eliminate and filter out the noise, others I just walked in, set up and turned on the gear to silence. Cheers Gary

I love mental exercises. I also have been known to engage in logic confusion, as in: Ringo Starr was the best drummer in the world because he was in the best band in the world. This drove my older brother nuts when we were kids, which just made it more fun for me.
To that end, using history as a guide, I'm seeing that the word: monobloc(k) - or term: mono block - has morphed, but in all the cases I can find, monobloc has meant a single unit of construction which can consist of multiple parts. Example: An automobile engine can have multiple cylinders but is expected (usually) to power a single automobile. I choose this example because it fits with the idea of a multiple channel amplifier powering a single speaker and, as boomzilla points out, each channel of which can be used to power each individual driver of a speaker. Put another way, is "a" speaker one driver? or multiple drivers combined in a "chassis"?
However, I would prefer that the word/term be associated with a single chassis mono amp because it means that all the parts of the amp are supporting just a single output and no more. Best of the best. Can't get better.
Mono+Block = 1 channel + 1 chassis
But if I am to be true to myself, I truly believe there is justification for multiple interpretations. So it's a draw - unless you think it's not. Either way, I agree.

( Did you know those processes are accelerated when it’s your Birthday 🎁) ? Instead of beating this thread to death any further, I’d prefer to share with you my Ringo story.... One of my earliest musical corroborations was with an eighth grade classmate by the name of Tim Cappello. I was a drummer and Tim was on keyboards. We played on and off together throughout High School and Beyond that for a while. He was also one hell of a sax player, and that set me on fire when I jammed with him towards the end of those days....anyway fast forward out of touch for some years and then I saw a Tina Turner concert on HBO, only to see Tim up on stage performing along side her! Not long afterwards, I find he had become the Sax player for Ringo Starrs band! I thought I was hearing things (LOL) when Ringo introduced Tim in that British accent of his! Bill

Well, for marketing purposes, calling anything other than a single channel chassis a Mono-Block would cause utter chaos. Perhaps we could come up with an even sexier name for multichannel single speaker setups, like "multi-modular amplification".
Let's try that out.
'Instead of mono-blocks, my two channel system uses multi-modular amplification'.
Yeah, that might work.

...Want a pair of short speaker wires? You pay the shipping and I'll give you a pair. Two, three, or four feet - take your pick. Boom I would like to take you up on this offer. send me a message and I will gladly pay shipping Hi lotaz - I'm assuming, since I haven't heard from you, that you have other issues going on (work? health?). I hope you and yours remain fit and healthy. In any case, my offer still stands. I'll be waiting to hear from you. Cordially - Glenn

Terminology used "forever":
mono(block) = one amplifier per chassis dual-mono = two independent channels in one chassis stereo = two channels in one chassis that share components like the power supply etc.
Speaker wire length: Other than aesthetics, the only technical reason I have found valid for matching lengths was to keep the effective driving impedance the same. And that is still only a concern with low-impedance dips (e.g. crossover) and wildly disparate lengths of small'ish cables.
FWIWFM - Don

With my Emotiva equipment, my home theater / home audio is already way above average. If you have to go with longer speaker wire length, increase the wire gauge accordingly. I have two ten foot speaker wires, so I went with 8 gauge. Do I need 8 gauge? I don't know, but it can't hurt. Bigger is always better, right??? Haha! I am not disappointed.
