TOPPING DM7 8-CH DAC : what can replace it?

@VeerK It is also possible (and probably less expensive) to use MiniDSP's MCHstreamer configured for ADAT, plus an ADAT audio interface. It's just as much of a hack as the DIO-8 plus four stereo DACs...
 
charlielaub, did you choose an a product ? i use an opendrc-da8 now and it is noisy. the software is great though. i am looking for improvement when it really makes for an improvement
 
No. At the moment I have several interfaces so I am not rushing out to get another one. But I always try to keep my eyes open for what is coming along...
 
ha, me too - i also keep my eyes open

Is that your own design? Very impressive.

I started out with the Hifiberry 8x hat for my project, but I found the physical layout of the outputs to be fragile. Single-ended and no volume control.

I'm now using a Motu Ultralite Mk5, but while you can set up the master volume to control all your output channels in Cuemix, there's no remote (except using Cuemix on your phone or laptop, which is awkward).

charlie can i ask you for chances for improvement ?

I had problems with noise and hum when I used DACs with single ended outputs (e.g. RCA interconnects). After I switched to balanced equipment (line level and amplifiers) that was gone. I assume your Hypex amps have balanced inputs, so the issue is probably (as you suspect) with the miniDSP Opendrc-DA8. If you like the miniDSP platform you could try their Flex HTx, which has balanced outputs:

It's a good product and has an IR remote control.

By the way, nice speakers!
 
the flex htx seems to be without FIR
phase-aligning the drivers and making Rephase phase corrected FIR crossovers is what i like about the opendrc-DA8
i have been thinking about using a raspberry pi with usb 8ch-dac, but it would take time and money
i am open to improvements but i can also enjoy the music as it is now
last improvements are :
1. the 3d printed front/back of 10F and 17D2.2
2. lower order crossovers + meassuring diffuse field upright at the lissening position + less tilt in the frequencyslope than i used before
 
Fosi Audio is working on multichannel dac
