Marantz SA-11s2 XLR Output Cap Need Help

[kchu1377]

Hi all,


I don't know much about electric circuits therefore I like to seek your help. I have a Marantz SA-11s2 and attached a picture of XLR/RCA output. I noticed there are four caps in signal path per channel (c405, c406, c430, c431). What would be the best cap for this application? Currently they are ELNA Silmic 220uf/16V.
1) Would Black Gate STD be better the ELNA Silmic?
2) I can only find BK STD 330uf/16V for sale, would this be OK?
3) Would BG FX 220uf/16V be a better choice if I can find them?
4) I’ve seen others replace two caps with 1 M-cap Supreme. If I replace c430 and c431 with 1 M-cap Supreme, do I just connect point 1 to 4 with M-Cap?
5) Would M-cap be a better choice compare to Black Gates?

Thank you very much in advance for your help!

Best choice, absolutely, is no caps at all. These are completely unnecessary dc blocking caps, and can be eliminated. A straight bit of wire will sound better than any cap on earth(unless lousy caps are being used to tame the sound of a bad circuit). The fact that the caps are configured in a bipolar arrangement is a dead giveaway that there is not normally any dc offset at that point. Can't believe they didn't at least have some sort of decent film cap in parallel with the lytics, as Sony & Pioneer always do in this situation on their upper echelon units. Anyway, just install jumpers of good quality wire & it'll sound as good as it possibly can.

If you want to be sure to have no DC on the output, use a cap. Tried a 4,7uF film cap to bypass the elco's and the muting circuit in my marantz cd6002. Worked without a problem and sound was a little better.
