Linear Power Supply?
Can someone tell me exactly what an LPS supposedly does to improve the operation of a turntable motor? Does it run more precisely at a given speed? Does it vibrate less? I have a SOTA Eclipse motor with Condor and Roadrunner. SOTA is coming out with an LPS option which they say is better than the SMPS wall wart, but I want to know exactly how it’s better. If less noise in my system is the benefit, then I believe I already have that addressed because I plug it into my PS Audio P20 power regenerator.
when i had an origin live turntable, the single most noticeable upgrade was to the power. after replacing the wallwart with a transformer, everything audible improved and til this day is the apex of my musical experience. and, til this day, i don't understand why a single transformer that powers the tt's motor could alter its sound so much. https://www.originlive.com/shop/tuntable-options-upgrade-transformer |
For the OP, as noted above, all electrical questions in high end are ... complicated. First perturbation, though, I'm inclined to believe that the elasticity of the drive belt would tend to filter out any micro-differences between a well-designed SMPS & LPS outputs. That said, I'm willing to assume that: 1) SOTA carefully chose the wall wart they currently use, and 2) they believed that an LPS *could* make a difference, tried it, and feel that it did. Maybe they'll let you try one out? Good luck with your decision! Please let us know if you take the leap. |
@lewm the difference is AC vs DC. doesn't deny the fact that providing tt motor with cleaner power is a significant upgrade in sound at least IME it was. |
I'm sorry. Where did I "deny" anything? I simply pointed out that the OP is concerned about replacing a wall wart that contains an entire power supply, which launched a discussion of switching power supplies (SMPS) vs "linear" power supplies (LPS) whereas your wall wart was (apparently based on what you wrote) a transformer. Whatever else constitutes the power supply of your turntable must reside on the TT chassis; it could be an SMPS type or an LPS type. Changing the transformer does not change the downstream characteristics of your PS, except whereas many times a "better" transformer may favorably affect function, at least to the ear. |
