As requested we WILL add a new filter. Just a matter of how fast we can do that. It's lunar new year holiday so it takes some time. Luckily it's not on sell either so people would be waiting anyway. And everything can be upgraded via firmware upgrade.How likely is it that you would add your own filters in this case?
To make a fully featured AVR, there are a lot of license fees to paid.. such as Dolby, HDMI, HDCP, etc..Topping should make a fully featured multi-ch AVR, or AVP with Dirac. I'm sure they'd knock it out of the park, as they've proven time and time again to put in a lot of effort into their engineering.
Thanks, and apologies if some of us seem over-critical of the filters on an otherwise exemplary product. Full attenuation as late as 24k just seems WRONG. ;-)As requested we WILL add a new filter.

I think their point is that Amir didn't mention it in the written review. I'm fine with it as it's very common with other products and no severe consequences in multitone, or distortion etc. But Amir actually talked about it in the video with quite a lot of detail. So that's that.Thanks, and apologies if some of us seem over-critical of the filters on an otherwise exemplary product. Full attenuation as late as 24k just seems WRONG. ;-)
As mentioned before, there is a price to pay for an "ideal" filter.
It is trivial to use something like SoX to get 160dB+ attenuation and full attenuation at fs/2 and 99% steepness so that frequency response is completely flat beyond 21.8kHz (for 44.1kHz sample rate), but I heard no difference, honestly.
What I said in 2018, don't know SMSL regrets or not at this moment
That's nice to hear! CoolAs requested we WILL add a new filter. Just a matter of how fast we can do that. It's lunar new year holiday so it takes some time. Luckily it's not on sell either so people would be waiting anyway. And everything can be upgraded via firmware upgrade.
This actually made me laugh - "I Know What You Did Last Summer". My first veiled threat on these forums, and from a manufacturer's rep at that. I must be doing something right and pushing some sensitive buttons.Amir has to talk about everything every time from now on? Go watch his video, he talks in much more detail.
BTW I know what you did on other forums. So I hope everyone is automatically nicer and more logical on ASR forum. Thanks.
I won't say I won't.[QUOTE = "JohnYang1997, post: 667855, membre: 5166"] Aussi la beauté de notre nouveau produit est que nous pouvons ajouter un autre filtre si nous le voulons. Tout ce qui se trouve dans la machine peut être mis à niveau (sauf le matériel bien sûr). [/ QUOTE]
Bonjour depuis la France ! Je possède un DX3 Pro 2 dont je suis pleinement satisfait ! Je voudrais vous demander : pour quelle raison ne sortez vous pas un DAC qui contiendrait un DSP avec un égaliseur paramétrique ayant une dizaine de bandes et serait aussi capable d'intégrer une convolution ?
For hardware, espeically a low power chip like these Cirrus Logic DACs, even if there is a freedom to implement a filter, the filter length (number of samples) is still restricted to a certain length. Think about playing an RPG game, when you "level up" you have some points to assign to your character's ability, there is a certain degree of freedom to assign the points, but the assignable points remain the same. That means, putting more strength in one aspect means putting less strength in another aspect. I think from one of the links I posted, the Okto has more ultrasonic spikes when using a filter with full attenuation at fs/2.Price seems worth it. As far as using SoX, it's trvial in the sense of it working great, but it's not going to be trivial getting it running from all sources.
Audibility isn't a concern, in the same way a 0.999999kHz clocking result isn't a concern. It's mostly a concern around these parts (people wanting to see displays of excellence)
Though I will grant one thing, this Topping D30 Pro implementation, at the very least, the filters dig real deep attenuation-wise. So even if they're a little late, they go down quite a bit and seemingly stay there without any concerning anomaly. So at least you get something back when not given the "ideal" filter
How do we know how good a value something is if we don’t know the price?This is a great performer and value, except for the lack of an strict, accurate filter option that others have pointed out.
You would think that a DAC with volume control and remote might be connected to, say, an amplifier.
Like many DAC reviewed here (that also have remotes) there is no trigger.
This looks like an evolution from desktop products that has not been completed.
Perhaps, if Topping added a trigger, the rest would as well. They all seem to following one another.
If not a trigger out, how about a decent powered USB port. A Raspberry Pi3 with DietPi can run as a Roon endpoint from a standard 5 volt USB port without under-voltage warnings. My MiniDSP SHD has issues with its Roon implementation so I run a RPI3 powered from the SHD USB port. A USB port on the PRI3 is connected to a custom USB power to trigger cable that powers the AHB2 on and off. Like many modern amplifiers, the trigger is operates with 3.3 to 12 volts detection.
@amirm And I would like to add that it’s nice for me to see/hear you.
I thought digital pioneers relied solely on analog reconstruction filters that were nowhere near as steep.Both are clearly faulty. The only reason they get away with this crap is there is so little "up there" in the first place. Digital pioneers would be turning in their graves.
And no, Topping are just lazy. No buck passing on LPFs back to the D/A manufacturer, what a joke.
