When you plug the usb cable it switches automatically to usb and spdif is ignored (there is a HC157 on board with selector signal tied to us power).

I just got a DAC7 and have been listening to it for a few days. I'm very happy with it. I've been comparing it to my "TDA1541A Reference DAC" (with tube output) and the DAC in my Denon AVR-2106 (which as far as I know uses AD1837 chips).

The AVR-2106 is a great sounding receiver with good DACs, but the DAC7 is very noticeably superior to the Denon DACs. I need to do some tweaking on the TDA1541A DAC because it doesn't sound quite as good as the Denon, and is blown away by the DAC7. Considering that some people have spent more on a custom transformer for the "reference DAC" than it costs for a working DAC7, I would say this little guy is a good deal.

I think this is a great buy and I would be interested to see how close it gets to Cambridge Audio's DACmagic. I would be surprised if it sounded much better than this.

Default dac7

I have finished the Dac7 from Weiliang. Wow! The dac seems surpassed the Cambridge. I have AD825's in it. Very nice. I tried some different opamps, not one is as good as this is. Have somebody used other opamps?
If you are looking for a dac, buy it (no connection with it).

Hi Weiliang,

Is it possible from you to launch PCBs with the chips (Te7072 and WM8741) soldered only? Or naked PCBs with the chips to solder separately? This would be very liked and helpful for and from DIYers who would like to build their own output stages/power supplies.

I personally would like to try the chip direct out, it has big capacitance drive (1nF).

Hello batalok,
Thanks for your kind share! Happy that you like the DAC7!
AD825 is good, I use 2 pcs OPA627 mono to dual, also is nice!

If someone want to have a try, assembled board is your choice, assembled WM8741 DAC7

Default Happy that CM6631 USB module!

OK, upgrade the USB module of DAC3 AD1955 DAC7 WM8741, using CM6631, much more better! This chip is great!

How does it compare sonically to the tenor 7022? Too bad, I already ordered the Tenor few weeks ago.

Weilang,

has the DAC7 WM8741 balanced out on the PCB?

Sorry, no balanced output.
