Thank you. I have searched for information on the 1-bit Topping D90 III Discrete and this comes up “Given the 1-bit architecture here, I was primarily using Roon with the D90 III Discrete to play my tracks in native DSD mode” https://www.techpowerup.com/review/...c-a90-discrete-amplifier-desktop-stack/6.html Does that mean it has the “dsd native direct processing” function or is it something else?

Thank you. I have searched for information on the 1-bit Topping D90 III Discrete and this comes up “Given the 1-bit architecture here, I was primarily using Roon with the D90 III Discrete to play my tracks in native DSD mode” https://www.techpowerup.com/review/...c-a90-discrete-amplifier-desktop-stack/6.html Does that mean it has the “dsd native direct processing” function or is it something else?
It has dsd bypass, which is nice to have.
Searching about the differences between DSD Bypass and DSD Direct I found this article very enlightening. The author spoke with a Topping engineer and it isn't the same thing https://www.euphonicreview.com/blog...-bypass-mode-on-akm-chipsets-once-and-for-all Topping doesn't implement DSD Direct. The S.MS.L D400 PRO maybe does, but it is not certain:At least we have DSD Bypass in DX9 15th, we will have to see if DX9 Discrete fully implements it.
EDIT: Someone tells me that the SMSL D400EX does, that there is a lot of debate with this and that the best guide to DACs that are capable of doing this is on the HQPlayer page.

It might be the same as the velvet.
I had the velvet for a week.
Sent it back after reading about the 19khz cutoff and no dsd filters.
I have huge collection of dsd and sacd.
It would be ashame if the new discrete didn't have bypass.
I use my adi2 dac fs and dx9 for my dsd.

In DX9 15th it does have DSD filters, so the new DX9 Discrete I guess it will keep them.

It will have a 1-bit chip. It is not very conventional.
Has info been shared in this or other associated product (ie D90 III) threads wrt
1/ architecture/topography/functionality/performance of Topping's discrete DAC replacement (system-on-board, it appears);
2/ will DX9 discrete have any increased digital signal processing capability such that new functions may be added, such as PEQ ?

I don't think the DX9 Discrete is going to have a Parametric Equalizer. That feature is being introduced by Topping for the first time in the new higher priced 900 series. I think the new DX9 will only have over the 15th a feature difference associated with its Discrete DAC. It was not possible to continue with the excellent AK4499EQ as the chips were limited to 1800 units. In my opinion you can expect in the DX9 Discrete some improvement in DSD playback and worse performance in PCM and general device measurements.

Probably, but Topping doesn't say anything about that.
But why is that important?
Do you know what femto-clocks are?

Anyone know how this compares to the Fiio k17 and the new Luxsin X9. Specifically the headphone out?

Both have significantly less power and slightly worse readings, but nothing audible.
Even a DX5 II has more power and at least as good readings as both devices, for a fraction of the price.
In a Facebook comment someone from Topping said the DX9 Discrete is going to be released in October. Do you think it is plausible? Also, do think there is a chance the price will stay the same (or below) as for the DX9 Anniversary Edition?

Well, it's a few weeks since they released the D900/A900, so another launch must be imminent!
As for price you'd assume it must be cheaper than their ultra-flagship D900, but likely more than its predecessor?
If it comes more expensive, then hopefully not by much!
I'm holding fire on the purchase of a Fiio K17 to see how good the DX9 Discrete is going to be.
By the way, do you think there is any chance of us ever getting a DX900? At that price point, one may argue, people prefer separates.
However, Chord Dave and dCS Bartók are DAC-amps...

First look at the Fiio K17 just susses me out. At that price point you'd expect Neutrik XLR connectors but instead they are ZWEE.
The DX9 is essentially a D90 Balanced and A90 Discrete plus two extra NFCAs in one box.
The D900 and the A900 are the same size as the DX9 so they will for sure make a DX90 or DX900 that's a little bigger than a DX9. The DX9 isn't especially big either for a piece of gear in the audio world.
The A900 and D900 aren't especially crammed on the inside either:
They could easily half the number of amplifier outputs to save space. The challenge would be to make it look good on the inside so it would be pretty with a glass top.
