Yeah, the phone can only do wrong. Can you hear instability when playing a recording with piano?
The SDS simply recreates a clean version of the voltage waveform needed by the AC synchronous motor.
Questions about VPI Turntables and rotational speed
I've noticed that my VPI Prime Scout is not as good as I'd hoped at rotational consistency. This has been measured by two different iPhone apps on my X. Now, I can get it to stay around 33.33 RPM, but it seems to have a fair bit of flutter. My thinking is that this could be caused by the relatively heavy weight of the iPhone X in a relatively small part of the turntable, whereas vinyl would produce relatively light weight, in across the entire platter. Does this sound right, or is the weight of the iPhone probably inconsequential?
That said, I know there are devices made by VPI (i.e. the SDS) that will cause a more optimal signal to the motor. However, I also know that speed may be varied fairly significantly by moving the motor closer, and further from the center of the platter. So, given this non-fixed ratio, how does the SDS serve to make a better signal for the VPI?
Thanks!
