Re: [SlimDevices: Audiophiles] Awesome news -- got my S-Booster
The s-booster would be potentially piontless . As measured with ADM by member iPhone the output of the Touch or SB3 does not change with another ps , there is difference. This is because that the squeezebox itself is filled with other switchmode PS that turns the raw 5 volts to other voltages that it is goin to use internally, so the raw supply is not that important .To make an real impact you have to Diy some more and redo the internal supplies. However there is the the problem that the not so expensive orignal psu can affect other equipment in the hifi system via rfi or emi or noise over the cables etc, this is a secondary effect and might not apply to everyone, as it is system dependent. That is basically why i run an 3 party psu myself not for the benefit of the Touch but not induce stuff to the rest of my things. (I got this PSU while using the SB3 it had a much worse original psu than Touch .) S-Booster still leaves you with the original PSU without doing anything for you ? -- Mnyb Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.

It's a 2nd order lowpass. It's pretty much the same setting as John's setup. The Sbooster IMO is not expensive. And best of all -- it works. Howard mentioned large improvement.

I know what I hear. That myth is busted. 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. -- adamdea adamdea's Profile: http://forums.slimdevices.com/member.php?userid=37603 View this thread: http://forums.slimdevices.com/showthread.php?t=86542 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
