Mijo, perhaps the modern or updated versions of the Star Sapphire are speed stable, but my late 90s Series III was anything but. At the time, it was all I had to judge by, and it had me thinking that it is the nature of vinyl not to be able to deal with sustained piano notes. Then I found out, after owning a succession of other turntables, that the star sapphire was the absolute worst in that regard. Every belt drive, idler drive, and direct drive turntable that I have owned since about 2000 is superior to the Star Sapphire in speed stability, and its shortcomings are quite easily heard. I do respect SOTA as a company, and rumor has it they fixed their problem, whatever it is or was. Surely they’ve now fixed it with the adoption of the Phoenix Eng control system. But please don’t suggest that speed instability can’t be heard.
LP12- Power Supply- Need education
I have read a lot about different options to upgrade the analogue power supply.
A phono stage need to amplify micro signal would require very good power supply to ensure there is minimal noise interfere with the signal.
I read about Lingo and other power supply articles, however they never mentioned about the science behind it.
How could a power supply powering a motor will introduce noise to the cartridge especially belt drive?
How do you measure the noise when playing a record?
Or would the power supply provide a more stable rotational speed, my speed measurement on the turntable shows very consistence rpm once it is playing?
I really do not understand why a Lingo power supply cost so much but cannot provide an improvement with a measurable results.
Could someone educate me.
