Topping DM7 8-Channel DAC Review

[jtwrace]

It would've helped Topping to actually send units to beta testers that use these configurations. I mean; it's no secret of who was requesting features for a MCH dac like this from the thread I started here on 9/21/2021. This in my opinion was a fail.

Unless you have a spatial setup. 2D surround is very last decade

Not to mention you don’t have HDMI inputs nor selection.

If you have the room and the wallet for a full on Atmos setup, go for it. Most people will probably be doing 5.1 or 7,1. Me, I do 5.1 over the PC, and view Atmos movies over my SMYTH A16 Realizer which does up to 24 immersive audio channels of ATMOS, DTS-X, and/or Auro 3D over my choice of in studio recorded Dutch & Dutch 8Cs + Pardigm sub PRIR or my home recorded 24 channel LS 50 Metas with SB 2000 sub PRIR binaurally rendering out to my HD 800s and LCD Xs.

They could come out with the required bridging device, probably HDMI eARC to USB then you could put your PC in the middle and do your DSP...

Perhaps this is just the first multichannel offering from Topping? In which case, I think it's a pretty good attempt... for the price.

Yes, thanks! We are screen capturing the same website just so you know!!! And seeing the same drivers on that website. The same owner's manual.

Ha, yes, corrected. I try never to go backwards in life.

A HDMI capture card might get you there, but you have HDCP to deal with. You’ll probably won’t get bitstream audio out of it.

Then why are you asking what is in front of your eyes?

I’m responding to your following post. As Amirm is talking about driver, the word “this” and “it” in your post means drivers too. I was trying to be helpful by telling you to refer to the manual which clearly says “it” is in their website.

Suppose I have the above configuration:
1) USB connected to PC and running Foobar2000
2) connection to active speakers as above

Does Foobar 2000 have channel assignment such as above or similar (the numbers above are just for reference)? What about SW cutoff frequency setting? Does Foobar2000 have cutoff freq setting?

Well, yes - I'm definitely familiar with the disappointments associated with Linux audio. But, in the overwhelming majority of cases I've looked at, it's the mixer/routing/channel mapping that tends to be the problem with these interfaces.

There are way more pro audio interfaces that do have issues with Linux + multichannel, than don't

There are a few Motu models well known to play nicely with Linux

But spend some time at Linux Musicians Forum to see all the issues

I'm specifically talking multichannel on Linux

We don't yet know about DM7 with Linux

Unfortunate but good to know.

Then have you read and participated in @dualazmak 's very comprehensive discourses on active crossovers for his speakers using an 8 channel DAC ?

Thank you @maxxevv for your kind description about my active multichannel multi-amplifier project using OKTO DAC8PRO.

Those who would be interested, you will be much welcome to my thread on multichannel multi-driver multi-way multi-amplifier stereo audio project. You can find my latest (as of May 30, 2022) system setup here. You would please find here (on my project thread) and here (remote independent thread post) the Hyperlink Index of my project thread.

For simple channel mapping you don't need plug in:

Topping DM7 8-Channel DAC Review

To be clear, I plugged in DM7 into a windows machine and used it. No software was installed. I used ASIO4ALL to talk to it which exposed 8 independent channels. So everything is class compliant so I see no reason Linux would have trouble here.

but yes,foo dsp xover has everything one needs.

Edit:For everyone who wants to play with multichannel SACD's:

 

[Peafowl]

Multiple inputs is not the point. If it had parity with OKTO in that regard you would for example be able to use a CCA as a source into the DAC, send to USB host for crossover DSP processing, and back to the DAC and feed into amps and have a clean active DSP speaker setup with no additional ASRC in the chain.

If you are looking for a all in one solution ... there you go https://analog-precision.com/home/upp/

But don't say it is to expensive because otherwise you would need 2-4 different hardware and software units to do the same thing.

 

[Peafowl]

Two of these running a 16-channel Atmos-system out of a PC would be a sight to see.

Is this what you are looking for?
What about a 16 channel Ultimate Pre-amp ? How about a 24, 32, 48 or more channel Preamp ?

It is a fun project but it is still in beta, and looks to be abandoned. The last and only activity is a bug report that was not commented from seven years ago. It was written for an OS that was introduced in 2004, and reached EOL in 2014. A lot have changed at OS level during the last two decades...

6.950 AUD but with all the others you get also this:

Hi I canot see the benefit of this example, because you create an multi ADC ,DAC chain. Attched the Hypex block diagram. This explains the internal Hypex structure.
Please help me to understand your example.

They talk about "DIY" multi channel hypex Amps not the plate-amps which includes an extra DSP.

Make me spit my coffee out! LOL.

The one that really got me was a JVC Super Digifine receiver, RX-1001V. I think it's around 100 buttons (many double ended) on the moulded back plate, under the front panel buttons and above the tactile switches. And every one, perfectly centred, supported and positive. Ahh, the 80s.

It was a retro beast. I have one someplace- you should see the remote! Full backlit touch screen LCD learning thing.

I had one of these in college. We referred to the backlit LCD as “Tokyo at Night”.

An UX nightmare. The UI is designed on a grid paper!
