Caiman passive output mod revealed

[OLED]

I was reading that site earlier as well, interesting if a bit diminishing returns ish. My original question was more to ask if the high rated dielectric strength causes any problems in this low voltage and current application? I cannot think of a reason why it should but would be interested to find out if there was.

Having some success now with the 6.3V version of the 47uF Nichicon Muse ES. More promising than the 16V version (brief listen did not impress me as much as the 6.3V version).

Nice sweet treble, excellent clarity and harmonics (about on a par with the Black Gates), extended bass and a quick break-in time. The delicacy/texture of mids and sweet/controlled treble gives a fast sound that's groovy when the music is groovy. Very similar to a Rega-style of presentation. Slight downer is that I could do with a stronger upper-bass (like the Rubycon NA has a good quantity of), but that may come in time.

This is fast becoming my favourite cap.

I don't believe a high voltage rated cap necessarily sounds good or bad, other factors are probably more important but it's one of those suck it and see aspects. Most aspects of hifi are about finding the best mix and compromise, with coupling caps this is very much the case.

The Obbs sound good but a but all over the place at the moment,however bass seems better and deeper than the Mundorfs.I suspect at these voltages they may take quite a while to run in.

Biggest problem though is that no two peoples systems are the same (probably) and definitely no two people here the same way. Suck it and see is spot on, not much science can do for us here, but it all adds to the fun of it.

I've got 28p worth of non polarised 10uF electrolytics from Maplin running in my Caiman at the minute.

I was astonished at how easy it was to perform the mod (open case, remove daughter board, fit caps, replace lid) as it never seemed to be as easy working on the TC7510.

The change in sonic output is not subtle - I'm going to run with this for a good while before coming to any conclusions.

Where did that extra octave of bass come from ?

Good innit?

You're not jesting !!!

Hello - first post - this is a FANTASTIC site.

I'm going to use the Rubycon 47ufs from the board to two new sockets.

My Marantz power amps are 30kohms input impedance. Should I be putting in a resistor in series and if so what value would you recommend?

Thanking you.

No, leave the input impedance at 30k, with 47uF Rubycons you will have a very low frequency roll-off anyway.

You probably need to get over to the welcome area to introduce yourself before the membership police get to you
