Quite a few low-offset opamps will allow dc coupling at output. As for the MKS caps beating all lytics i am not convinced at all. Perhaps they will be an improvement over the stock caps.

I didn't argue , that they will beat all electrolytics. There will be a sonic improvement against the orginal equipped one and longterm stability will also be improved. A further improvement may be replacing the 1206 resistors with Mini-melf resistors, as suzyj showed in her investigations (better THD).

@ merlin el mago
The lowest voltage available is 50V and the maximum capacity is 10F with pin spacing of 5mm (acc. https://www.wima.de/wp-content/uploa...WIMA_MKS_2.pdf).

Maybe try with Nichicon ES bipolar electrolytics first. In terms of distortion these caps are extremely clean.

Ok here is what I did with the phono module:

I drilled some holes for the leads of the WIMA 0.1uf



Put the opamps (OPA827) and the caps in place

Bipolar Output caps C451 & C452 changed to Elna Silmic II in following way:

Each cap should be 4.7uf. I soldered 2x 10uf back to back (+-|-+).
The resulting cap measured 4.8uf. I would keep it if you think it is ok this way


Thank you very much!
