Topping DM7 8-Channel DAC Review

[windfr]

OK, I was wrong, it is just necessary to define a channel mapping in output to have ASIO + DSD running 5.1 files while it is not necessary for ASIO and ASIO2.

Real success but what a PITA!
Here's playback

I got MC DSD128 to work with other 5.1 files but Lisa Jacobs was still silent (but no error message). The great bird of inspiration shit on my head and I realized this is a 5 channel file. I mapped a 5 channel entry and viola (actually violin but who's quibbling?)

How many times I said "channel mappings"???
Give 32 bits to toppings get rid of unwanted devices (uncheck them on the left) and enjoy your music!

I'll just build different profiles for different scenarios. I've got a diverse library of MC music. Given the vagaries of different schemes, amongst the engineers and channels, it's necessary. The real PITA is the 5 channel music won't play on 6 channel mappings but 6 channel will play on 5 (an issue unique to FB2k in my experience). Most classical surround DSD music I have is 5 while, the jazz, blues, folk etc is all 5.1.

I'm going to stick with J.River but this was a nice exercise. The OP bought the "2016 L'Arte del Violino (Locatelli Violin Concertos) - Lisa Jacobs, The String Soloists (5.0)" on my recommendation to play through the DM7 and had trouble with FUBAR1900. I wanted to see if I could make it work.

To avoid to have to change the channel mapping with 6ch , 5ch, or 4 ch, I use channel mixer with this configuration.
For stereo this config add sound on rear speakers.

 

[dartinbout]

I have certainly used this to convert stereo to surround but I am kind of a stickler about my multichannel DSD albums. You really can't modify them much without (IMHO) changing them. With the DM7 and J. River I can get it as unmodified as I like. Everything else is just adding baby laxative to "blow". I know this site loves to EAPO, transcode, and MiniDSP the heck out of them but that's not how I roll. The "Lisa Jacobs" violin and my other classical albums are works of art, I don't f__ with if them If I can help it. FB2K is fine, just like HQPlayer, Aurdivarna, Roon are all fine, but to me there is just some layer of compromise. All of them have drawbacks, to me..

 

[windfr]

If you want to stay in stereo with channel mixer you let the volume of the rear pannel to 0 in the upmix pannel.
The first pannel is only use to send the right channel to the right speaker without changing anything in the sound. This permits to use the same DSP with 6, 5, 4 or 2 ch.

I think you're misunderstanding.
We use EQApo, miniDSP and co to un-f__ our favorite music from the f__ery that is most speakers', IEMs', and headphones' stock frequency response.
We EQ not to change the sound, but to preserve it.

I've certainly familiar with the sciency part of the approach but I only compare what I hear my system reproduce to my 50+ years of experiencing live music in San Francisco. I live 4 blocks from the Davies Symphony, Jazz Center, San Francisco Conservatory of Music and Opera House. I've spent thousands of hour in 100's of live venues, large and small, open and sadly closed. I've come to the audiophile world, quite late comparatively. So my question is, just what are you trying preserve? Most of the sciencey approach seems relatively hypothetical compared to the music, as it's performed. IMHO audiophilia is just a form of musical pornography. It looks like sex, sounds like sex, stimulates the areas of the brain as if it was sex, but pornography just ain't sex. Just like playing recorded music isn't necessarily music. /r off

Thanks to Sokel and Dartinbout for their help. I have followed their inputs and every kind of variation until I am just worn out. I am indeed listening to the Lisa Jacobs .dsf files in glorious 5 ch sound through my DM7. However, the DM7 is reporting PCM 192khz, so there is a conversion going on. Every time I get foobar to send DSD to the DM7, although the DM7 reports DSD, all I get is noise in all channels. I'm beginning to think the problem lies with my computer's USB output capabilities.

 

[windfr]

With SACD configuration, for DSD, the standard ouput is Dop; to get a Native DSD you can use Transcoder. Did you try it ?

Do you use volume control or some kind of DSP that alters it somewhere?
Have you installed the drivers properly?

 

[windfr]

I believe that this disc is in DSD 256. DM7 accept only DSD128 max. if so PCM 192 is the best solution.

Or use the DSD processor to convert it to DSD128,that's why is there for.

Nope - the disc is DSD 128

Yes, I've tried with DSD Transcoder. I have seen foobar output that was DSD 128 but the result to the DM7 is always noise.

If the output is valid is either volume control used,bad or long USB cable.
Can't think of something else.
And of course ASIO drivers,only.

No volume control or DSP at all. Have I installed drivers properly? I think so , the Asio+DSD: topping USB Audio Device - 5ch driver is working with the DM7. The Foobar output spec is DSD128 | 28224kbps | 192000 hz | 5ch and the DM7 reports PCM 192kz and all 5 channels are playing.

 

[dartinbout]

Ok root analysis.
These will be snippets while playing the Jacobs.

!st install the new version

Install the right components

The front panel says DSD 5.6
The control panels shows

Driver is 5.30.0

Firmware is 1.17

FB shows

I find it important to not have an LFE for this. We can address other scenarios later

If you want to rule out OSI layer one BS. Install the trial J. River, select the DM7, don't modify the format and channels. do the bitperfect


This can be done.
