Gross & Fein DAC Direct Headphone operation

Recommended Posts

The other day while testing some new DAC firmware at home I needed to do a quick audio check.

I was in my office with the DAC connected to the PC so just on a whim I connected my 64 ohm Sony MDRZ 1’s directly 

to the RCA outputs on the DAC with some adaptors.

I was quite surprised at the strong output level & sound quality I was getting.

At 75 on the output level it was getting pretty loud.

I just thought I would mention this as it might suite some users wanting a simple DAC/headphone setup.

Now I would only recommend this if you have reasonable high impedance headphones - 64 ohm or greater.

The headphone impedance is reflected back to the DAC chip output stage so can’t be too low.

 I will do some checking to make sure the DAC is protected against overload  but in the meantime feel free to try it but just don’t run the volume too high.

 I’m sure it will be lacking in the bottom end but anyone keen to try please do  - some feedback would be appreciated.
