The sound difference between Elna Silmic 1/2 versus Elna Cerafine

[RoboCopper]

The amp is AMC 2445, so if you can find schematic would be nice.

I will stick with Silmic 2 and hope that they sound better with burn in.
Thanks

Sorry Roberto I cannot find the schematic anywhere. I would really try to push you into checking/setting the bias though, it will be worthwhile.

Last night I left burn in disk to play all night.

It is maybe my psyche but the sound is warmer, more "analouge" and easier to listen to. At the time of refreshing caps, I also included new RCA cables to burn in, hence too many changes happened at once. I hope that burn in gives further improvement. So far my guess is that I did 80 hours.

How would I find out bias settings? Contact manufacturer?
