Your measurement?
Maybe I am blind. What is the measuring bandwidth?? 22Hz - 22kHz, 22Hz - 45kHz, 22Hz - 90kHz?? Thank you. How many harmonics of 6kHz base frequency are included?That’s why it’s listed below the graph.
Not good enough according to @Willem though. The RME degrades the performance of this amplifier.My RME outputs +24dBu, with 12dB gain from the amp that equals ~300W/8Ohms.
My point is that the way this was tested to not even close to being representative of 99% of real world use cases. Unless you think 32W is an acceptable output level. If that is the case you better off just getting the Topping amplifier...4V DACs will drive this amp in its tested configuration (12dB gain) to ca 32W output power.
I am not sure what your point is.

Never seen the film and was unaware of the quote (just had to look it up).Thunder was being sarcastic. Or at least I think he was...
Which makes 1706€, VAT and shipping included to France.Rouge Audio Design (IT), who did sell OEM amp board from Hypex (and Purifi and Icepower) launghed the N-7X with 2 NCx500 boards for 1385€ excl VAT.
True - but we still need to know the measured bandwidth - which has a significant impact on the meaured THD+N Level. If not there is no way to repeat your test.Harmonics outside of the audible range don’t matter. Which is why the 18+19khz CCIF IMD measurements are what is typically used to measure distortion at the upper range of human hearing. As well as any 2nd order effects that could cause distortion at other frequencies in the audible bandwidth.
And the first finished amps are in store i see, Rouge Audio Design (IT), who did sell OEM amp board from Hypex (and Purifi and Icepower) launghed the N-7X with 2 NCx500 boards for 1385€ excl VAT. They use OPA1612 opamps as buffer and the Hypex HxR discrete voltage regulators and the Hypex SMPS1200A700 PSU. So very stock...
Audiophonics (FR) is also busy developping their take on it i hear from people close to the guy behind it, and so is Sound Import/SoundImpress (NL) are taking a look at it. So most of the usual suspects in Europe will soon have amps based on this board it seems.
Hi Rick,One interesting aspect of the NCx500 is how much light it gives off. The reason for this is twofold:
View attachment 257309
- The vertical regulator boards have sets of red LED arrays that light up as an H.
- A bright white LED (seen below on the middle right edge of the board).
Do these serve any function? The data sheet does not indicate. The NC1200 has comparable regulator LEDs. The white one is close to a thermal sensor, so my best guess is it may indicate thermal overload.
what does bandwidth mean in this context? I get that you're intending to send a specific frequency to the amp... is bandwidth the area you're looking for noise?Yes it’s 20-20kHz. Any wider bandwidth would provide misleading results. Which is why professionals do the 18+19khz CCIF IMD test.

The tests have been updated with 27dB gain buffer enabled.83% of people gave this a golfing panther when it's super hard to get the wattage out of it... that's confusing to me.
I'm excited to see what this module can do in an amp with a good buffer stage and may buy one if it still looks this good, but I wouldn't want the amp configuration as tested.
just when I thought I'd get to fall asleep...The tests have been updated with 27dB gain buffer enabled.
I recognize the font at the bottom... is that from an internal Hypex datasheet?
Hypex NCOREx THD vs Power 1kHz-6kHz @4 Ohm.
No the measurements have adapted to provide information that’s actually useful.
Fair enough - you appeared to be particularly knowledgable about the amp tested here, and also seemed to be defending it - hence my assumption.Thanks. No I’m not associated with Hypex. I believe Hypex has their own account here already.
