Hmm. Sounds like a marketing thing to me. Any plots/measurements?
What about the output of a power amplifier?

Benchmark say the same thing about AHB2 power amp. Speakon connectors have lower distortion. Of course, people often use banana plugs with binding posts and many of the plugs aren't very good.
I did say measurable, not audible. I think Bruno is on a hunt for the final distortions. I haven't trawled the Purifi website to see if anything is published, but I'd already decided to go speakon 5 years ago.
When John Atkinson says
you have to consider whether he thinks the behemoth monoblocks so loved of some high end manufacturers are the past?
I would like to see evidence that connectors have measurable distortion. My CLT-1 has a distortion floor of -170dB with generic binding posts. Maybe those are limiting its performance???
My view as well Demian.
Seems if something’s got ‘Neutrik’ stamped on it, all sorts of claims can be made.
That said, no more accidental shorting amplifier outputs with Speakon connectors and maybe that’s the real benefit.

Except the distortion can be measured, whether it's audible is another matter, it is cumulative.
Me too. The Purifi crowd are not known for making things up so if they say measurable (however low) they must have had some way..
But I was more interested in knowing if anyone had a good reason NOT to use speakons.
Of course, big linear amps are not the future! They are the best that we can offer in the present day. '-)
Why, it must be those who are truly obsessed about it, just like Amazon is "obsessed" about its customers.
Who else but an "advanced audio listener" would worry about how the clock circuitry in their router/hub might effect how their audio reproduction sounds...
30 years ago in a text based Audio forum, one guy stated "I know some of you are going to tell me to "get a life", but these changes really did make it (an FM tuner) sound better". He was definitely an "advanced audio listener".
Isnt a (digital) Class D amp essentially a 1-bit DAC that can output the required voltage and current to drive a speaker? Perhaps their proliferation is in part due to the digital storage and transmission of audio these days; why bother to convert to analog until the very end, the speaker?
The future of Audio will be wireless direct into your brains, call it class W(ireless)
No more problems with hearing losses.
That will make all current hardware obsolete.
No more struggle with the family about the size of your speakers, etc, etc.
Maybe Elon Musk will be the innovator that puts the whole audio industry upside down.

When I was at primary school we were asked to draw a picture and explain our vision of the future, mine was a man with an aerial sticking out of his head and he was able to "watch" TV directly in his brain......
Might want to step back and (re)learn the various ways that a class D amp may be constructed. Almost all of them take an analog input rather than a digital input stream, even the "direct from digital" amps, which are oftentimes an DAC + amp in a single package.
Economics are going to say that IC-based amplifiers are far and away the most common, and monolithic class D amps are "good enough" while maintaining so many advantages in terms of energy efficiency (and the downstream cost/size reductions in amplifier infrastructure).
It'd be disingenuous to say they don't have their respective compromises, depending on design goals. You have the tour-de-force class D types as well, which are certainly interesting in their own right.
And I say this as someone who powers his system off a pair of tpa3255 evm's. It'd behoove me to finally get around to getting an additional 6 dB of PFFB, if for no reason than I have too much gain in my system as it stands.
Any large industry has problems moving to new standards. The "RCA" connector has been around to 70? years, starting as an RF connector in radios. Its universal presence (must be at least 10 billion in service world wide today) makes transitions really hard. The shift to HDMI was a real challenge for the TV industry and retail pushed back hard. Now there are over a billion of those in use making a shift in that industry really difficult as well.
The speakon has some clear benefits but no obvious performance advantage over a good binding post. It also means you need to terminate a cable to it which in the classic world of zip cord to binding posts makes them less useful. Also looking at the available panel versions you get PC mounting or 1/4" faston (not something to use if you are touting superior connection qualities) or solder or screw connections but none too compatible with large gauge wires. Certainly not the same as soldering a 10 AWG wire to the back of a big brass post. note that both the big superior binding posts and the speakon are rated at 30A max continuous: NL2MD-H | Neutrik http://www.farnell.com/datasheets/1...wu2K41S51AOye7DzfGCwVHhHu9t-jpW8aAkwKEALw_wcB I can attest to passing 3000 amps through a binding post on a regular basis with a very low duty cycle and short (100 uS) duration showed no deterioration over many years.
