<p>It's worth noting the MC-202 and SH-101 use bog standard ceramic caps for their filters (C48-51)!</p>

<p>I have 2 Serge Res EQs, one with styrene throughout and one with a mix of ceramic and film caps. Both sound great.

<div><font face="Helvetica">Right! I tested C0G vs polystyrene in a hi-performance VCO some time ago and they behaved identically, as far as I could tell. More recently, I tested both in my low-leakage S/H experiments and was able to verify leakage down into
the low fA region for both types.<br>

Didn't Ian Fritz teach us that NP0 is just as good as polystyrene?<br>
(Provided you can obtain a cap of the correct value of course.)<br>
<br>
Right now all I can find is this message in the archives:<br>

If Ian has more to say I would love to hear it...<br>
