Experience with this DIY DAC ? - Page 48

samoloko · 15th May 2009, 06:02 AM

examining this dac designs I see

cs4397 and cs8416 - two pcbs - one ne5532
cs4397 and cs8416 - one pcb - two ne5532
cs4398 and dir9001 - one pcb - two ne5532

which of the 3 is best
I think first - It Is claimed to do 192 kHz and you can do mods - change tha caps
the ones with dir 9001 got lesser jitter but no 192 kHz

what are your choices

samloko,

the dac i bought has the cs4398 with the 8416

it has input transformer on spdif

just thought i'd let you know there is another option to your list, which i personally thought to be the best option

Actually, I think that the best is to buy the one with the upsampling board and USB and adding a digital transformer at the spdif input.

If you don't like upsampling, you can use it without the upsampling board

I agree completely, I didn't think I would like upsampling, but I was wrong. YMMV

I'll write a transformer battle soon. Here are the candidates

Yamaha Tamura GA80080
Lundahl LL1690
Digitec
Little Studer uncapsulated
UTC HA-108
Chicago A-xx

Take care Marc ! price will increase on ePay with such revelations

just send me your choice under personnal email

much more secure

how Is edcor 600 / 600 doing
are you test It

Mush · 15th May 2009, 08:37 PM

I didn't get the 600:600

I got the 10k:15k for experimental purposes.

I haven't had time to wire it in. I will try tonight. I know it will take several days to break in so I'll report sometime next week.

samoloko · 16th May 2009, 05:23 AM

could any experienced person explain the role of the audio transformer used in output stage and also what has to be the type 1:1 600/600 or whatever and why

fordgtlover · 16th May 2009, 08:48 AM

Sorry for the silly questions.

In legarem's diagram in post #418, the black wire is connected to the ground connection. Is that the analog ground of the DAC?

http://www.diyaudio.com/forums/attac...amp=1241223954

Also, on the same diagram, is the type of capacitor across the transformer primaries important (0.0047uF)?

Bill Fuss · 16th May 2009, 10:41 AM

Those aren't silly questions.

The caps should be good quality polypropylene film.

The grounding issue is best answered by legarem, I wouldn't think it wise to defeat the isolation provided by the transformer by connecting one side of the secondary to the audio ground.
