Now I don't want to appear slow, and i would have to admit to having had rather a good lunch; but could you help me me by identifying what it was exactly which "busted" the "myth". Oracular though he may be, John Swenson's endorsement of a particular circuit design would still fall short of conclusive evidence of its efficacy. However, since it is clear that the S-booster's circuit design is at best a bit like John Swenson's, and since his message is quite clearly that any deviation from his specs is potentially fatal, any general similarity is clearly not enough to piggyback off (doubtless unimpeachable) prestige. So what exactly was it that "busted" the "myth"? I genuinely regard myself as an agnostic on this front, and have been on the verge of buying a linear power supply. But each time a little nagging voice in my head has baulked at spending something like the price of a touch on its power supply. Several years ago I bought a mains filter from ebay which did not cost very much, an had numerous ecstatic testimonials. Funnily enough I eventually concluded that it did nothing noticeable to my system. Actually the S Booster is quite cheap, but since as far as I can tell from JS' analysis the only real benefit of a PS upgrade is reducing the noise generated by the existing PS into the rest of the system, before i buy one i would love to see some proof that it does so. Mnyb's post suggests that he was under the impression that the S-booster does not affect the noise injected by the PS: it strikes me that this is a verifiable proposition. I accept that this would not prove that the output of the touch was beneficially improved, but it would at least move the debate along.
