Weiliang DACs - any opinion?

post #1 of 13
Thread Starter 

I see the Weiliang DIY products discussed some on diyaudio but not this model.. I notice it has a 3.5mm headphone out.. it doesn't say if it's a line out or amped though..  I have a dac/amp that has some hum when the dac part is used so I was thinking this might be good to use, I could run rca from it to the back of my aune t1 dac/amp.

He also has this one on Ebay....looks like his top of the line DAC with the AK4399 chip:

Not sure what the AK4399 sounds like compared to CS4398 though..

Any update on DAC9?

Got today this DAC: http://www.ebay.com/itm/141247672853

Hasn't listened much yet, but for first opinion, it does sound good enough to be a definite step up from my Matrix mini-i (2012).

Any one else using Weiliang DACs? Any opinions?

 

Does the USB sound better/worse than optical? (I didn't order USB module, so cannot compare.)

I have the akm 4399 and like more the xmos usb input, but I tested only optical input with a samsung cheap blueray player.
Now I ordered the newest version with akm 4399 ak4118 dual r-core.
Yes, I like the sound of weiliang akm 4399 dac + ada4627 so natural and detailed, my best bargain in hifi

I agree, it seems to be an amazing value for the money.

I have a Weiliang DAC9 based on the AK4399. I have purchased both the XMOS and the CM-USB Card, but neither seem to fit inside the DAC enclosure! There are just the respective holes on the PCB, no adapter socket or the like to fit the card. Even if there was a proper socket, the dimensions of either card are definetely too large to fit the enclosure. I am pretty confused as I have purchased a "finished" product. Has anyone had a similar experience? Neither the DAC seller nor the XMOS card seller (ebay:minishow0328) comment on the issue. If you have solved the issue, could you post a pic? I cannot imagine I am the only one with this problem...

Thank you smily_headphones1.gif

A friend of mine has a DAC7, the toslink input was DOA and the CMedia USB board holds with a piece of foam hah: http://www.imagebam.com/gallery/udjqujhpwsbpuhobf03619pkac4mtxwo/

Thank you! Looks like the pins of the card were resoldered vertically as well. Using foam to cushion the card in this unstable position seems a good idea. Still I have no idea why these Chinese DACs are sold without an option to have the card preinstalled. AND the enclosures are all too small, so the cards need to be resoldered. AND no seller makes mention of this mess anywhere in the descriptions. No way to grow a loyal customer base for sure...

the layout is just very, well, 'unrefined'. the power supply regulators are far away from the chips and the bypasses are too far away, just to name 2 obvious observations on the board layout.

so, what I'm saying is that it's a working config but its clearly not an optimal layout. to be fair, I don't expect expert layouts from ebay style boards and I knew it was a budget board when I was buying it.

 

It's prolly a great DAC if your main hobby is messing with audio circuits, this is semi-DIY at best as far as I can tell and I'd send it back for a refund if I were you.

@bioport
Why don't you use optical input? It sounds awesome (though my DAC isn't exactly the same as yours).
