I don't see any since there are many different measurements that have been performed. If anything I feel the noise performance is underappreciated. It's the most important thing in normal listening situation after frequency response.If you could add something to the common suite of measurements for each type of component, or revise an existing one, what would they be (if anything)?
In short it's because DM7 was sold quite poorly. And there are other challenges like thermal, power supply, cost etc.Why doesn't TOPPING produce multi-channel power amplifiers? It doesn't need to design supporting software. It produces an 8-channel power amplifier. Buying two can be used for the 9.1.6 system. How perfect.
This is a real customer need, this is a real potential market, why don't you do it?
I don't see class d reliability as something special. Our issues mainly was due to potting. But there must be solutions, because power supply units have using it for ages without issues. It's just that we have to make the testing before production a couple of notch more hardcore.In your opinion, what is the greatest enemy of Class D reliability?

It's nonsense.I saw some people talking about lack of driver protection and such in ehp5.
Is it nonsence or will there be ehp5 plus with updates?
DM7's competing product, Okto Research, is close to bankruptcy? The AV market is in full swing. I also hope that you can do things like AVP, just support Dolby Atmos, you don’t need any other functions, you don’t even need DTS, of course you must support Dirac Live. Produce something that really has a market, the DM7 is destined not to have any sales, I think you should also produce a 16-channel DAC, which covers a wider range of people, or at least supports ADAT.In short it's because DM7 was sold quite poorly. And there are other challenges like thermal, power supply, cost etc.
It's called qualifying. Test them to the thermal limit and cut out the poor performers. Otherwise cease hiding behind potting compound and keep innovating and hope for familiarity and loyal customers.make the testing before production a couple of notch more hardcore.
Yes and no. It's not so difficult to just slap a dsp chip in a dac.Is adding PEQs to DACs difficult?
*wink*
Regular qualifying doesn't do it. Well it takes more than a week and 60c+ to make them repeatedly fail. If not accelerated it took 1-2 months to see failures in 20 devices. Doing a few times then a year passed.It's called qualifying. Test them to the thermal limit and cut out the poor performers.

Then, why not skip the potting compound? Topping/TP seems to have a loyal following. I doubt anybody is going to copy and make money.Regular qualifying doesn't do it.

And you know in grand scheme we are still a small company with 45 people or so in total including the factory. And hiring knowledgeable people is difficult that's a whole other issues we have to think about.

When will service manuals be released? The big companies like Sony, Marantz, and Denon offer service manuals for repair and longevity. Maybe it can even be done for out of production units only.Anything related. I answer them as much as I can.
