I'm planing to upgrade my alpine PXA-H800 opamps
I already upgrade my power supply caps too nichicon now i.want too change out the jrc 4580 opamps as there
General use and not for audio i seen lots of post some use the opa 1642 others use AD823A and the opa1662
And , were there any other modifications done for the opamps to work in place of the njm4580 or can i just use jrc 2608 any suggestions on a good audio opamp replacment for the H800 and what work well

Change of opamps in a H800 is possible, but you have to have the smd soldering skills to do. There is also a blue kit used for protection (?) over some of the components, which you have to remove first very carefully. PCB traces are easy to damage.
JRC2608 is just a little "better", I advice the OPA1612 or 1642, low power consuming opamps.

. Hoping the noise floor is lower than the h700? - Status
