I'm going to mod my amp to use with 300 ohm phones. It has enough power to drive them connected to speaker out but there is some constant noise. so I want to mod my phones out. What I have to do? 325 ohm resistors out and thats all?

Im cutting 680 ohm resistors out and replacing 325 ohms with ~80. Then resistance to amp should be same that with 32 ohm phones.

no, I'm keeping 680 and changing 325 to less. There is voltage and current issue.

That helped me, I have to make some learning and calculate more.

but It will work
