HI all,
I am currently having a problem with my PPA V1. I recently purchased a pair of Denon D7000 headphones which have a 25 ohm load. I initially built the amp with a gain of 10, but with the Denon's I had hardly any volume control. I then changed the gain to 5, which gave me more volume control, but I m having another issue.
Whenever I listen to music, the llouder I make it, the signal clips, I get distortion in the music. The amp is using the OPA627 op-amps and is wall powered by a steps power supply I also put together. Are these headphones too much for the amp, or could there be something wrong with the amp itself?
I have ruled out the headphones by plugging them into different sources.
Thank you for any help you can give.
