ground loop

Good morning to all,

Before I begin, I welcome Alan's initiative to create this forum.

I am a proud owner of a P452 which has impressively increased my listening pleasure on my system ...

But that's not the point!

Even before being a customer at March Audio, Alan had been kind enough to answer a problem that was materializing in my house by a consistent crackling on one of my speakers. Where Topping hadn't had one which had cost me an exchange under warranty of my dx7 pro.

Alan had diagnosed a ground loop problem when I plugged in my DAC which caused a compatibility problem between my different audio components. This problem should have been solved either:

- by changing a device of my system (node 2i , dx7 pro, pre + amp YBA at the time 😉 ) ;

- or by using XLR cable

Thing done with my P452 + XLR <=> dx7 pro.

But that sizzle persisted.

So I took the initiative to use a schuko plug that I had, to isolate the grounding plug from the DAC with tape.

. And there ... nothing more !! what a relief ...

The approach of this post is twofold:

- that my experience can be useful to others ...

- ask a question: can this operation harm the elements of my installation? and will I reduce the sound quality of my DAC over time?

Thank you for your attention and have a good end or beginning of the day !
