Sennheiser HDVD800 Headphone Amplifier - Page 155

There was a time when I would like to know from someone I trusted that what I was using was a good example. But that time has passed. If it's music to you ears then it is. This hobby is filled with what is good and what is not. But as I do the same its sure nice just relax and enjoy.

The output impedance of the SE-out of the Senn amp is 16ohm if I'm not mistaken, 43ohm is the output impedance of the XLR-out. So if your Grado is plugged to the SE-out, then the damping factor should not be too much of a problem.

thanks... I didn't know that. It was indeed the SE Output.

The single ended is 43 ohms output impedance,and the balanced x2 20 ohms, making 40 in total.

I have opened, measured and modified mine. Now mine has 10 ohms single ended and 20 ohms balanced on the left connectors of each type.

Would you be so kind as to show a pic of the mod ? I am assuming there was a out put resister you eliminated ?

Please post pics and a diagram if need be. And thanks. Lastly how did effect the hd800 sound or did it at all.

And no stability issues with the chip amp? 

 

How's the sound with HD800?
