Twindac+ and Django (BD-Design)

If so, wouldn't it be even better if the output trafo of the twindac was itself a volume control, i.e. a trafo with many selectable outputs? You would spare a trafo in the signal chain which should result in even better signal quality. What do you think about this?

Hi Wolfgang,

I discussed this with the designer of the TwinDAC+ because it seems a good idea. Less is more!

In reality it seems in this situation that things will be worse. Here is what he wrote to me:

"I do not think that will work, as you have to load the DAC in a correct way. Furthermore, you will change the winding ratio with each tap on the DAC transformer, which will have other negative effects on other parameters.

It is actually not a good idea to attenuate the tiny signal at the source. The output transformer acts as a passive pre-amp and the attenuation should be done on the amplified signal."

Ciao,

Bert
