Audio Precision alternative

[Sokel]

Multitone It's free easy to understand and can do a lot more than only multitones. I wonder if there is still work in progress about it going on?

About Multitone?Tons of work from @pkane ,join the thread to see,I think it evolves geometrically.

I service, repair and sell used Audio Precision systems. They do sell for well under $2000 on Ebay however you don’t know what you are getting. Many end up in my shop. I do offer many extra help for my clients. Please Email me for any info.

I'm a former AP employee and left to help launch a low-cost alternative (that failed). In a nutshell, nothing comes close to an AP in terms of feature breadth and technical specs. Of course, you may only a subset of the capabilities in which case there are many alternatives. For instance, an AP can handle 300 Vrms at the input. How often do you need that? If you need to test a high voltage load, you can always measure across a small sense resistor and convert your results. I wrote an article on this. https://audioxpress.com/article/practical-test-measurement-attenuators-for-measurement

There are plenty of other features aside from specs that separated AP from the pack. This includes their breadth of digital interfaces (I2S, PDM, HDMI, etc) and their automation software and some really specialized measurements not commonly used in consumer gear. Their dominance is so strong that Rhode & Schwarz exited the audio business. Prism (Spectral) is a shell of its former self and I think the only reason Stanford still sells the product is to clear inventory. I have a friend that reps the brand and he tells me the SR1 gets no interest.

People that don't need all the hardware specs of an AP can still benefit from their 50+ man-years of software development by using APx-Flex. This allows their software to be used with the hardware of your choice. Echo Test & Measurement sells boxes that are compatible with this.

So basically AP has a monopoly on the market.

Looks like HP also exited the market long time ago as well.

Whoever can crack the code by being able to bring a cheaper alternative to the market is going to make waves. Too bad your venture didn't pan out.

They make simply the most advanced gear in that particular market. That's all. But to make the best amplifiers you don't need it.

Can't even measure a $10 headphone dongle properly.

How much does this audio analyzer cost?

Hum.
I always find IMD figures from AP quite low, indeed.
But I think there is more than just a hardware difference at play here.

I'd be curious to run the same IMD test with APx500 flex software with a known device like an RME ADI-2 Pro, as an example.
That would then be easier to identify the methodology-induced differences.

Last Unit i have a receipt for was around 7000€ - there was one or two options included and this was almost 10 years ago though.
