wm8740

[takashi]

do any one have experiences in using the dac chips of "Wolfson Microelectronics "?
for example, WM8740, it has 117db SNR, 24bit 192kHz...
can anyone share the experiences ?
thanks

I heard some rumour that Wolfson is inside X-box but I have never heard of Wolfson in any high-end.

I have 2 samples, thought they were cool but cooler chips have arrived...

Hi weissi,

Did you ever get the wm8716?

 

[weissi]

yes, now i got them..... but I haven´t used them anyway - no time for this things yet..... I am still on the search for an "easy to mod" soundcard where I may replace the onboard dac with them....

Wolfson WM8740 DAC

Hi,
While at my dealers showroom I stumbled upon a Arcam CD33 FMJ series Up-sampling CD player. It uses the Wolfson WM8740 DAC. Arcam apparently gave up the ring DAC.
The DAC chip is available from Wolfsons website for $ 8. Funny to see pricing in $$ instead of GBP's or Euro's on a UK based company's website.😉 Anyone has a listening experience with this DAC???

I Reckon They Are Good.

A while back, I did some improvements to a cheap (AUS$200) DVD player that used WM8746 DACs.
With good supply bypassing, the results were quite outstanding, and better than most CD players.
For the money, these chips work very well indeed.

Eric.

Hi All,

Glad to see interest in Wolfson Products! I work in technical marketing for Wolfson and stumbled across this site when checking out our weblogs. I'd be happy to field any questions from you guys on any of our stuff.

and just so you know we have our 8740 designed into SSL, Korg, Mark Levinson, Arcam, Rega, Harmon Kardon, Onkyo, Yahama ........... the list goes on!

I could go on about the architecture of our sigma delta modulators as to why our DACs sound better ... but i'll leave that one for another day!

and yes it was our DAC in the XBOX

Cheers,
Stephen

Hi Stephen!

Why do you think your DACs are better than that from TI/BB or AD? What are the sonically advantages?

As I know all current delta-sigma DACs based on a digital process and they are all 6-bit DAC with a delta-sigma modulator. The only High-End manufacturer is Mark Levinson or shall I better say Harman?

Cheers
