WEILIANG DAC5 - WM8741 & Tenor TE7022

[vinodt1347]

Unfortunately its in Russian which I cant read. Try
The Buffalo-IIISE (Stereo Edition) 2-Channel DAC

its quite famous in diy circles costly tho. There is a ebay seller diynhk
ES9018 32bit Audio DAC PCB kit | eBay

vinodt1347 what acoustic system you have that could not hear difference?

 

[vinodt1347]

Could be my ears !! its a mosfet based diy amp a P101 ESP product and B&W 685 speakers.

vinodt1347 musicality of this device and the Dac (ES9018) overdone and inflated as producer (great marketers bother) and manufacturers like Buffalo and other (audiolab). It sounds like a typical Dac average (not like the cheap of course).

Unfortunately its in Russian which I cant read. Try

there was a circuit of dac.

and I repeat, does anybody have a measurement of DAC7 or DAC9 (by Weiliang) in RMAA or others???

 

[vinodt1347]

Hi, I cant afford to get a ES9018 DAC and I think you may be right not sure how much better it can get. Dont get me wrong. The DAC7 and every other DAC do sound good.

Got a little question:

How many of these Klick do I need to replace the opamps of a DAC 5?
Looks like there are two included but what is the sense of that dual to mono adaptor?

Regards

2 pieces, the sound is much better

DAC by weiliang with possibility to disable digital filter and interpolation

To weiliang:

Hi weiliang. I want to buy some DAC from you.
Condition is that "data" will by passed through DAC directly to analog without any interpolation, oversampling, under sampling, without any use of digital filter.

I want to use DAC to measuring purposes. I need that exact digital value of input will do exact voltage or current value on analog output, include DC value of course.

This can be done by software setup (by windows) or hardware setup directly with pins on DAC chip. I can do both.

Please recomend.

audio dacs are not 'instrumentation dacs'. they dither (as one post-process step) and try to make the wave sound 'good'. this is not the same job as an HP or tektronix measurement dac.

not sure you will be happy with audio dacs. depending on how much resolution you expect, of course.

 

[BKSL]

I will be happy with 16 bit resolution but I need only pure sampled data without any computing.

Hello,

I got a little problem with my DAC 5:

Always when the deep tones come, the highs sound strange. They're sounding like the DAC got out of power and very fading...

Already ordered some OPA627 but I don't know if they'll solve the problem...

You got any advice for me?

Regards

 

[WaterCooled]

In addition the left Channel is a bit louder than the right channel, but I might be wrong with that cause that's subjectively...

It just sounds like the deep tones are mixed with the highs and that sounds very strange. Sorry for the description, it's very complicated to describe that sound

 

[phase]

Mine sounded about like that until I had nearly 50+ hours on it.

All fine now.

 

[WaterCooled]

Alright, that brings me some relief Thank you! I'm about 20-30 hours now and it already got better than a few days before but it's still there and hearable at a little higher volumes.
I'll wait then


Regards

 

[phase]

And when it starts to sound good, the opa627s will show up in the mail...

Start the process again, to a degree.

Am listening to Miles Davis, with some brush action on the drums, and it sounds pretty clean, except for the hiss from the recording.

 

[WaterCooled]

Hehe that's what I fear too but it's okay

The DAC already sounds much better It's still there but you can only hear it when you fucus on!

Regards

Does anyone know if the TE7022L board requires the usb 5 volts to function?

I am preparing an improved USB cable, and wanted to know if I need to buy a regulated P/S or not.

Thanks
