DAC 5

What do you think about this other project? :

I'd like to have a backup plan in case I don't find pcbs and mounting manuals for the RetroDAC....


thanks gain!

nonos problem

A little OT but this web site quoted above

http://www.geocities.com/yury_g/dac.htm

talks about a phase shift problem with nonos at high frequencies due to the delay caused by the serialisation of right & left channels - however reading up in this forum and the net no one else implementing nonos DACs seems to know (or care).

Can anyone shed some light if this is really a problem?

 

[fedde]

Well, first of all this would not be a problem of non-os, but of I2S. Besides, I think that the TDA's compensate for this...

I also like the layout and the product seems to be good, although it could be improved further

Did you hear the Ack DAC ? What could be improved ? Still experimenting with your TDA1543 DAC !?

Reclocking would be a definite improvement. I didn't try this DAC.

In other thread, I mentioned that my modified Marantz (TDA1541) was better than TDA1543 stand alone DAC. Well, it was better on my previous speakers, but on the new monitors, ( http://www.diyaudio.com/forums/showthread.php?s=&threadid=16237 ), TDA1543 DAC sounds better (smoother and cleaner). Part of that might be the simple passive output stage and good PS and reclocking. With Marantz, I just change the output op-amps and didn't touch PS except for changing electrolytics and adding bypass.

Hmm, this is what I see...

Okay, this explains your comment
I see a totally different layout, so it must be due the way in which it was coded. Maybe certain browsers/versions interpret it differently?

When I first read your post and looked back at the webpage, it couldn't figure out why you thought it was a bad layout. After I saw the picture you posted, I can see how you didn't like it

Does anybody know of a DIY dac with balanced inputs (AES/EBU) and balanced outputs? Other inputs (SPDIF) are a must also, and of course switchable..

M-audio SuperDAC 300 Euro and available in the Netherlands.

Use the Search function for more info.

-----------------------------------------

M Audio has fake balanced output; single end to balanced conversion, as I remember.

 

[jean-paul]

I thought it was symmetric, please see the datasheet of the AKM 4593 DAC. The M-Audio has the same schematic.

AN Silver wire transformers

Would it be possible to get hold somewhere or similar Silver Wire Transformers a la AN DAC 5.
Maybe even having a very small bunch manufactured if a few of us joined together??

Hello,

AE Europe is a dutch manufacturer which normally supply tube freaks..
http://www.ae-europe.nl/audio.htm

Mind you, the amorphous core transformers are very expensive.. about 800 euro per two. But these are specified at 25 Watts. Maybe the manufacturer will produce a few smaller units..

I have the 2496 Superdac. It's definitely not balanced in the analogue output.

What do you think about this

Whoops! forgot to say that I was talking about a pure silver transformer.

 

[fdegrove]

Hi,

Whoops! forgot to say that I was talking about a pure silver transformer.

Actually, you did mention that.

The point is though they don't need to be 25W.

If there's sufficient interest I can talk Wil into building anything you need from copper to silver even gold if it must be.

I'm sure that he can reduce the price considerably once you spec the needs correctly.

Cheers,

I don't know where I have specified before that it was pure silver.
Of course you only need enough for a signal level transformer.

It's also nice that he builds to spec, as I thought..

If there's enough interest somebody could get the specifications together (line level, hopefully usable for both digital and analog unbalanced to balanced).

I am not sure about kits but for my money the perp technologies dac P-3A with Modwright mods is amazing value.I have done most of the mods myself and it really is now a heavyweight contender.P.T. offer a a version of this I think around 800USD.

Hi protos & others,

I seccond that!
I know the PP DAC P-3A, this is one piece of equipment that beg's to be modifyd.

If you have one, don't ever turn it off if you haven't modify the power supply (cap's) otherwise, you'll have to wait at least 24 hours before the P-3A sound at it's best!
