Something that may be a revelation, look at the datasheet and notice that as the sample frequency goes up SNR goes down...

I doubt that. You cannot beat a crystal clock
It actually uses a crystal to generate the clock. Or I should say it uses an external clock, it would not have to be a crystal. 🙂
Hey, Russ. I was looking at WM8804 the other day, and was very interested. Only problem is I think it will be difficult to source, especially in the US.
They need to be purchased through Wolfson's distributors, just like the DAC chips. We have a relationship with them now, so it's pretty straight forward.
Beam me up Scotty
Hi Guys
Ok i tried to read the last 45 pages and not froth at the mouth too much. I have heard wolfson dacs spoken of with regard.
Ok i admit to having the ambition to build a tda 1541a dac non o/s with tube outputs
Could someone bring me up to speed as to
1. how feasible to output to a tube stage?
2.is oversampling de rigeur? or can that be customised
3.any experience on the sounds of 1541a vs wolfson dac?
I would appreciate anyones insights into this particularly promising thread
Regards
Nick

Re: Beam me up Scotty
Hi Nick,
1. Very feasable, just need to be sure the input impedance into that stage is >= 1K.
2. It can be customized to a degree by changing between 128fs and 256fs, or by utilizing software mode, but we don't provide a controller for that yet. Personally I would not touch it.
3. This one is dangerous to answer, as many like those old chips. All I can say is that to me the difference to me is night and day. I have a NOS DAC and have heard others. While some may find them appealing my personal opinion is that they don't please me.
Cheers!

Hi Russ
thanks for replying so quickly
I have several marantz players featuring the aforementioned silicon but i cant for love nor money procure any tda1541a's(genuine ones that is) so is there any other dac that is warm, musical etc? so what differences have you found? i respect the fact that you may not want to answer that but of all the current dacs, the wolfson gets very good reviews and at the price you are charging, well its not sell your grandmother territory ( i mean its great value)
Can you use two dac boards into say 6dj8's or 6sn&'s (my favourites)
I admit that as long as the source material is good, cd's sound darn good on my setup.
I understand your opinion is just that. but i would love to find a suitable alternative to the "old dac"
Thanks for your time and i hope your genius is truly rewarded with your project

Re: Thanks
Thanks Nick. You are very kind.
Here is more of my personal opinion. 🙂 I actually find the NOS DACs that I have heard anything but warm. To me they are fatiguing and sometimes overly bright.
I wish I could answer your tube questions, but alas, that is one part of the hobby I have not really pursued, at least not yet. 🙂
I think you may like the Opus sound on its own. Later you could easily add a tube buffer at the outputs.
Cheers!

can you or use 2?or not
Hi Again
Ok point taken re old stuff..
I see alot of dacs and designs (not that i understand it all) but it seems many designs utilise two dacs... is there any point.
I have a srpp 6sn7 preamp (single ended yes) so i would need the converter as well
thanks Russ

Re: can you or use 2?or not
Yes you can use two DAC modules each one handling a mono channel. You gain 3db SNR and the DAC should be able to handle a bit tougher load(more current), but thats the only difference.
The BAL->SE converter is open on my desktop being finalized right now, and will be ordered by the end of the week.
You are certainly welcome.
Cheers!

Hi Variac
Hello and yes i am...
HAs anyone tried to buy the 1541a?.. i havent found any genuine ones yet and the ecdesigns dac is a tad out of my price bracket... it is a work of art. it uses 8 dacs in parallel .. maybe one day
Thanks for the tip though

Hi,
more informations about opus dac and CD pro 2 with I2S
the response from the company where j have baught the CD Pro 2
"How to connect the opus with the CDPRO2 with I2S"
You probably can't. You will need a masterclock also, which the CD-Pro2 does not provide. SCLK is BCK, WCLK is LRCK and DATA is Din. But you still need the SCK. You can get a 16MHz master clock, if you solder the missing connector on the CD-board (which voids the warranty...). This will only work if the Wolfson DAC can work with a 384x clock, and not just 256x.
Otherwise you need an external clock (if the clock and data do not have to be in sync - check the Wolfson data sheet), an S/P-DIF receiver or a PLL to regenerate the clock.
ij j have well understood , j have several opportunities.
- J'am buying the spdif module, but j'am loosing the advantages from the I2S
- j'am using the internal clock of the CD pro and need to solder connectors and verify if it is ok with the wolfson. the original clock do not have a great quality.
- j order an external clock, like this one (8,4672 or 16,9344)(http://www.selectronic.fr/recherche_produit.asp and j follow the instructions from here

j hope to test my opus this WE with the spdif receiver of "maousse" in order to verifiy if all is OK

Re: Re: can you or use 2?or not
Hi Russ,
I am look for a DAC with 2 line out or possible 3 line out.
Well, I wanted to build dipole speaker driven by 3 amp and would like to stay with passive attenuator. Since your DAC is modular, I wonder if 3 set of line out is possible.
Never know until I ask. 😀
