This depends on the type of solder used. Flux residue from rosin core, and especially water soluble solders, should absolutely be cleaned. Although the board may work without cleaning, flux residue from these solders can cause undesirable parasitics between unexpected circuit paths. Sometimes the effect goes unoticed. Other times it severely impacts performance or causes strange problems (unstable and/or overheating IC's).

If you used a no-clean solder, there's no need to clean the board. But you probably didn't use a no-clean solder if you're asking.

Hi Stefan,



My name is Tomas, and I have ordered an ODAC past 15th July (Order no. 00197).

Three weeks ago, you said that you will send a new device from Germany at 15th August.

I have not get anything yet and I don't know if you have done a new send.



Regards,

Tomas.

I thought the rest of the forum can know as well, I missed to send out above order for Tomas.
I sincerely apologize for this mess up on my side and will see to it that he will get his ODAC at the soonest.

Sorry Tomas...

Best Regards, Stefan

Is there a reasonable way to convert this to balanced output?

To quote one of the designers:

'Reasonable'.. no.** you might point the fellow to NwAvGuy's latest blog after loading a few times there are some questions and comments on the value of balanced output.

my amp (ncore) is being used with balanced only inputs. I need a dac with balanced output. It isn't a question of value.

Hi Stefan,

Received my Odac and Objective headphone amp both standalone earlier this week. (Order Nr 00000296). The headphone amp is working properly however the ODAC is giving me problems.
Tried on iMac, Windows Laptop (lenovo) and in both cases only get garbled sound, very distorted.
On the mac tried with Audirvana + player as well as iTunes and on the Laptop tried with Youtube movies also getting the same result. I can hear the music but distorted with lots of static in between the audio.
Further tested with different cables, different ports etc.

My other 2 DACS Audio GD NFB10 and Matrix Dac are working fine.

Any suggestions ?

Hi Peter,

As per the mail sent earlier, sorry for the hassle. Replacement will be in the post tomorrow (actually today...)
I had one once before with the same issues, there it was a cold solder joint on one of the jumper traces.
