Tom, Ralph at Atma-sphere offer 2 options, as I recall...teflon caps, AND an upgraded power supply. Depending on the year of production, the S-30 may or may not have a regulated power supply. I ordered my M-60 Mk 2.2's with both the teflon caps and upgraded power supply [more caps], and later had it upgraded to a regulated powers supply. Big difference in fidelity!
And when you upgrade through Atma-sphere, you also get a brand new warrantee. Let Ralph do it the right way...he's one of the last remaining independents, and a hell of a knowlegeable and nice guy as well! And a track record of 20+ years doesn't hurt, either.
