Question AT LP60X buzzing when connected to amplifier

[lines]

Hello everyone,

So I recently bought a Fosi BT10A amplifier to use my new speakers with my LP60X. Previously, I had my tt connected to some active speakers using a male to male 3.5 cable and everything worked perfectly, no buzzing. Now, however, when the tt is connected to the amplifier using the same connection, buzzing can be heard. When I go to play a record, the buzzing stops immediately once the platter starts spinning. When the record finishes, the buzzing starts again. I've tried 4 different cables and the problem's persisted across all 4. However, I've found that the buzzing is slightly less noticeable when I use the initial cable I've always been using that has a silver tip and a completely flat bottom. The buzzing remains even when the tt is disconnected from power and I've moved the tt around and away from other electrical devices, still, it buzzes. If I turn the volume down on the amplifier, the buzzing becomes quieter and vice versa when louder. The amplifier works perfectly with my PC that I have connected through my DAC. I'm slowly starting to lose my mind here so any help would be much appreciated

How have you earthed your turntable? The Fosi doesn't appear to have any facility to do so.

I haven't - I understand this sounds like a grounding problem but from what I've read online the LP60X carries ground through the aux output, hence why it has no grounding terminal. And yes, the Fosi doesn't have one either.

So, logically, it is the Fosi amp causing the issue.

But that wouldn't explain ⬇️

I don't understand why though; I have it connected to my PC and it's playing music perfectly. No buzzing or anything.
