Received Aiyima A04 green board. Replaced thermal paste with Arctic MX-4. Tilear HD325x Rev: 2.1 is written under the radiator. Replaced 10mF capacitors with Elna rbd 10mFx25V. At the exit of Nichicon FW. Then I will put the original Epcos 0.68 mF MKP. The op amps are not like the original. Temporarily installed from another device. I will change to OPA2132PA.

Well done, looking forward to know how it sounds )
Updating the inductors should be a good choice as well...

My main amplifier class EA A. Laikov V6. I noticed that the cymbals became a little louder. I liked Aiyima A04 more. Otherwise, I did not notice the difference. Perhaps OPA2132PA will be better.
