Has anyone upgraded to Mundorf Silver / oil or Gold / Silver / oil capacitors? If so what were the main improvements you experienced with the ST-70?

I haven't yet but I've heard great things about them. One of these days I'll check them out.

The Mundorfs with oil are suppose to be good...

I have both the Russian PIO and the Mundorf Silver In Oil caps as input options in my SP-14 preamp ... and there is not much between them.
I have yet to have a chance to have a critical listen between the two ... but the differences would be subtle rather than obvious.
Well thats my 2c worth anyway.

I have the two different Mundorf's in my SP14. My subjective impression of the difference in sound between the Silver/Oil vs. the Gold/Silver Mundorf's is such that the S/O are smoother with less top end. High frequencies are somewhat down vs. the G/S. The difference is not huge, but noticeable in direct comparison. Bass and mids are practically the same.
Imaging wise the sound stage of the G/S is clearly wider and deeper. Classical orchestras or small Jazz combos are equally well reproduced.
On good recordings I definitely prefer the G/S. The S/O are a bit more forgiving with bad recordings as they seem to round shouty edges a little bit off. They may also be the better choice if one has brighter sounding components in their setup.
Just my two cents.

Thanks for all your feedback (or should I say input!) I replaced some Auricaps in a Joplin (DIY HiFi supply) 2A3 PP amp I made 8 years ago with some Mundorf GSO coupling caps. The soundstage really opened up dramatically to the point I had to re-position my Klipsch Forte's a bit. I have been told the GSO's are the "global reference" for coupling caps. Just checking. Very happy with the ST-70 now having eh Russian PIO's - but always fiddling around!

How many hours on those PIOs? Way I hear it, those can take up to 400 hours to break in properly.

Oh I would say over 200. I heard that was the "magic" timeframe!
