And they well deserve thatThey know their market. I suspect that sales of tweaky stuff "subsidises" the rest to some degree.

First harmonic of 8 kHz is 16 kHz. How many of us can hear 16 kHz?But still, passive loudspeakers with passive crossovers and most driveunit are way, way worse . But the Benchmark is really outstanding if we are looking at technical perfection . But one can argue if anyone can hear the difference between 0.003 % THD + N or 0,1 % THD+N at 20 kHz. I sure cant hear it.
Genelecs white paper says that amplifier distortion should be about 10 times less than the distortion from the driveunits, in the midrange .
If a 5 inch woofer has a distortion of 0,5 % at 400 Hz then its good enough with an amplifier that have 0,05 % THD.
Further, in another white paper Genelec states that distortion at frequencies higher than 8 KHz are difficult to hear.
I reached Audiphonics and the answer is "no". There is no clipping indicator by default on this amplifier.Does anyone know if the only LED in the middle is also used as a clipping indicator ?
Thanks
That would be the norm on most Purifi-based amps. Unlike the Hypex modules, the Purifi 1ET400A does not have a clipping indication on its simple hardware interface.I reached Audiphonics and the answer is "no". There is no clipping indicator by default on this amplifier.
Rocking? You need to adjust the feet or put it on a flat surface! ;-)Been rocking their NC252MP model for nearly 2 years now, good stuff.
950W, best case scenario (not with Hypex SMPS). Ask @boXem | audio about it.1000W @ 2ohm?
It doesn't suggest any such thing. It just is presented as evidence that there's lower distortion, nothing more, nothing less. What you're attributing to magic of balanced connections is quite commonly nothing more than a result of the design of the equipment.But many times we also see distortion artifacts significantly reduced when using balanced instead of unbalanced outputs, suggesting that noise on the device output is being cancelled as well.
In mono configuration, the 950W should be reached even with a Hypex SMPS. The caveats with the Hypex SMPS are about powers that are voltage limited (8 Ohm)950W, best case scenario (not with Hypex SMPS). Ask @boXem | audio about it.
But I could swear they're moving. Even my wife saw it!Whatever you heard in those shops, listening to different amps, could better be explained by blood pressure, caffeine intake or glucose level. Your ear is not a reliable instrument, it's prone to misinterpretation of reality, just like your eyes:

Only through measurement (put your mouse pointer on one of the rings) will you be able to get a glimpse of reality (the rings don't move about).
There is no scenario where you are able to reliably detect a difference between NAD C298 or HPA S400ET by ear. Anyone telling you differently, is likely talking out of their butt.
Pick your purchase based on a few key performance indicators, like power and SINAD, then looks, features and price, because these almost state of the art devices have objectively no sound of their own. Acting as if they had will just cost money and annoy a lot of ASR people.
There's always folks looking for bottom dollar bang-for-the-buck. I do it myself, sometimes. However, when making comparisons, one has to factor in the total package. If you live in France, or possibly the EU, this item is a no-brainer. Like Topping would be, if you live in Shenzhen. If you live the the US, other things come into play.Yes, if purchased by an American consumer, VAT would be subtracted off the price but then import duty would be added, and who knows how much that would be!
The other way around is true too though. Balanced connections are great, I wouldn't say that everybody "needs" it. And yes some manufacturers will also try to convince you of that. If you have no issues in your system it's also likely that you will not hear a benefit. It's great but not an absolute must. Many of us have many unbalanced sources to start with. Personally I have a balanced preamp and power amp, many unbalanced sources, a SUB with only RCA in. but lately I wanted to add DSP in the chain. And I felt the balanced options where not worth the premium for me. and you know what there is nothing balanced in my system anymore. It sounds very good, no noise no hum no audible distortion and the benefit of room correction.No they don't. If they don't have a balanced solution, they will try to convince you that you don't need it.
But could she see it from the kitchen?But I could swear they're moving. Even my wife saw it!
No doubt, it is a very good amp but I am a bit peeved with amp manufacturers who build low gain amps. They can usually claim very good noise figures but in reality they are simply passing the problem on to the DAC and/or preamp.
Yes! She's a trained viewer and ran right in asking if I'd changed something with my monitor. Mind you, I hadn't said anything. Incroyable! Étonnante!But could she see it from the kitchen?
Can anyone explain the difference between these 3 products to me? I have some understanding of the differences but not completely. Thank you.
