I don't get it.
It’s like the Marantz SA-10 where it doesn’t use a single chip IC but converts everything to DSD (1-bit) and implements an ultrasonic filter…
What are the advantages? Thanks.
Thanks for sharing!
So bad you have not captured @JohnYang1997 in the pictures.
What does a 6 channel headphone amplifier do?

Never had 2 friends around for a headphone party? You have never lived!
(I dont get it either)
Probably none. Marantz themselves insist that it will measure worse but that it allows them to have more control over the filter and dithering which they believe affects the sound.
I think it’s important when you hear them say it measures worse but the trade off is that they can apply some of their preferred algorithms.
See this post in thread 'Marantz SA-10 Review (SACD Player & DAC)'

I really enjoyed my SA-10/PM-10 combo but sold it due to budgetary reasons. (downgraded by 2 ch setup to upgrade my HT setup). If I was wealthier, I would have kept it.
I presume the "discrete" refers to the DAC and that the DAC is 'R2R', correct? ("Discrete" could also mean refer to substituting discrete circuitry for op amps in the analog stages.)
Sounds like Topping is pandering to audiphool trendiness.

You can see it on the D90iii discrete image above, but the D50iii and other unreleased models will also have this feature. d50iii will be available next Tuesday!
They call it a 1-bit DAC and show this
The LA90 Discrete outperforms the LA90 standard one, so I would be surprised if this measures that poorly. The SA-10 is almost 10 years old now.
These are delta sigma designs still, not R2R necessarily.
If you use Google Translate, you can see why Marantz went for it

And there was an interview at the same site with the developers where they say part of the development was engineers finding that things that had more noise sounded better. There has never been a solid ABX or blind test showing that you can hear the differences but I did show that the PK metric leans toward Marantz not being crazy.
Two reasonable DACs with a large PK Metric when tested with real music...
I've previously shown that my SA-11s2 and Panasonic UB9000 sound similarly and measure similarly with DeltaWave. In this post, I'm sharing some preliminary data showing a) a measurable PK Metric difference between two reasonable DACs with real music b) the DAC with a ~10 dB worse 1 kHz SINAD...

Yeah, probably none.
Almost every manufacturer (of everything, not just audio) touts their design decisions/trade-offs as features or advantages.I've never heard a difference/defect from a DAC, including the one that was built-into my 1st CD player. (I did have a noisy soundcard once that made noise when the hard drive was accessed, but I don't blame that on the "DAC".)
You can plug-in 6 headphones at once.
I assume the firmware allows you to adjust the volume individually but knobs would be more convenient. Multi-output headphone amps are common in recording studios, radio stations, and other professional situations.
I also see multiple connector types so you don't need adapters to plug-in a headphone with different connectors.

PEQ is certainly of interest... although I expect they meant except there in brackets.

I take it that this isn't the same as the Philips 'Bitstream' of old/Technics MASH type of circuit which claimed to be a kind of 'one bit' decoding...
Cool
