Topping DM7 8-Channel DAC Review

[run51]

Hello
can you tell me which linux ARM64 players(single board computer) are compatible for multichannel playback
thanks .other than roon and audirvana

Thank you

I'll have to repost my question. I saw in the thread that multichannel WAVs play back perfectly via android to the DM7. Did anyone try to do internal decoding of dolby/dts with the shield and output it over USB to a DM7?

I can report that multichannel MKV, DSF, Flac, WAV and DFF files will play from an android Samsung tablet, using varied applications (VLC and Foobar 2k). I truly love the DM7. Except for some really ridiculously crazy "thick" PCM and DSD\DFF files (above DSD128 or PCM 192), it handles everything.

Reviving the thread because I found a DM7 to try out and wanted to briefly return to the question of channel mapping on the Topping when the number of channels isn’t 5.1. I plan to use EQAPO at first.

Does anyone have any experience with this? I don’t have a center channel and don’t plan on getting one anytime soon, but I have two subs. This means that I’d either use L/R in Stereo with two subs (2.2) for music or L/R + rears with two subs (4.2) for movies. I guess my question is banal, but - how well does this constellation work?

I’ll find out myself soon enough in any case and will report back with my experience

I don't own this particular device, but I do manipulate channel layouts, and in Windows, Foobar2000 is the only app I have working with multiple devices and setups. Just add the Matrix Mixer component and WASAPI component. JRiver works too, but I switched devices and couldn't figure out the mapping. It will probably work but I gave up on it and just use Foobar when I need to map decoded Atmos PCM files.

I am using foobar2000 with DM7 (ASIO).

foobar2000 ASIO configuration allows you to remap whichever foobar channel to whichever DM7 port. Very flexible.

Mine is mapped L=>1 R=>2 C=>3 C=>4

(My foobar C-channel is actually used for mono subwoofer processing due to fb64 mixer limitations.)

 

[jeffaegrim]

Cool stuff, very encouraging, thanks! I also just re-read the whole thread and man, we sure are easily led astray in our discussions sometimes. Informative as usual nonetheless, just a bit more noise filtering needed for this one

 

[boxerfan88]

For reference ... below is the screenshot of foobar2000 ASIO configuration page that allows you to map fb64 channels to DM7 outputs.

did you get a chance to try it yet?

Sorry for the late response - been busy lately. I did in fact manage to set everything up as outlined in the post above. For the time being, until I find a proper center speaker, I have a 4.2 system that can reproduce multichannel content. Navigating channel mapping, which never ended up working in peace and had to be done in stock apo (to which, like peace, I developed a love-hate relationship), windows audio driver bs, output to REW, and various other little things that just aren’t quite perfectly intuitive coming from, say, a minidsp platform, was, however, a pain in the ass. At times I got frustrated and went looking for a real (encompassing all possible functions) alternative to EQAPO and wouldn’t you know it there isn’t one. But yeah, it all works, if you accept a slightly less user friendly experience, you can do (almost) anything you want with it. And I strongly advise everyone using EQAPO to also install peace, bc eqapo is almost unusable without it in complex configurations

no problem, I just ditched my 2x4hd for apo + voicemeter, with fir filters its been 99% solid with a hiccup every now and then, I might try peace, I've heard of it but never looked into it

I might try peace

Peace is a dumbed down version of the stock EQApo configurator.

It adds some features like clipping detection and AutoEQ database for quick preset loading, but it's much less configurable and IIRC is limited to PEQ only.

oh, maybe I'll use it when doing friends systems for them then

I've also just dipped my toes into FIIR filters, not as many guides as PEQ out there but seems very promising, so I'll need to stick with regular APO anyway I guess

It’s just a visual interface for EQAPO. With it there is just way less visual clutter, especially if you run more than two channels. I use it for EQ, HP/LP filters and delays - the stock configurator can still be used with peace activated. I can’t imagine running my config without peace, it’d be a mess to look at/work with.
