I am loving the sound out of my new Sprout 100. When the source is bluetooth, digital, or analog, and I crank the volume to the max, the speaker output is dead silent. Wow!
However, when “vinyl” is selected:
- With no input connected, it emits a loud hiss. Clean white noise, but it is there nonetheless.
- With my Technics SL1200mk2 connected and grounded, it emits a pulsing/stuttering/beating sound
Now, with my old Onkyo and cheap TCC TC-750 preamp, I get the same “noise”. But with a Pro-Ject Phono Box preamp, it is dead silent. Impressive.
The noise is likely caused by my wifi base station which is a couple feet away from the unit, and a couple feet away from the turntable. It is audible, albeit softly, when the Sprout’s volume is way down… and very loud when the volume is maxed.
I have read the “steps to troubleshoot noise” in the manual, and I get it.
My question is, how has your RF shielding of your Sprout 100 been? Does it emit loud white noise when on max volume with no input on Vinyl? Do you get any RF noise when the turntable is plugged in?
I was surprised that the Pro-Ject box is dead silent while the Sprout is not.
I know that a solution is to move/relocate stuff but I’m looking for a baseline of expectations here. I am new to PS Audio and the Sprout.
Thanks for any insight. (I will try to post a recording of what I am talking about.)
