Hi,
This is a simple problem but driving me nuts trying to fix.
I have a ground loop,
I have a PC directly connected to a Rotel RB-993 power amp for surround channels and to an RC-995 pre and RB-991 power amp for the front two.
An Avondale Arcam Alpha 5+ is also connected to the RC-995.
If I disconnect either the PC or the CDP the hum goes.
All the earths are connected, all one circuit, all low resistance (I'm a sparky, do not know electronics, but can fix a dedicated spur well. )
I currently use a ground loop isolator between the PC and RC-995, but it really messes up the quality (but fixes the loop).
I want to fix my ground loop, but do not like the isolator.
I just read that using an XLR can fix the issue!
I didn't know this, and not really sure how it would.
I currently have XLR between my pre and power, but could fit modules onto the CDP quite easily.
This leads to the questions.
1: Do XLR fix a ground loop issue?
2: Are there different qualities of XLR and can they affect sound quality?
3: Something like this work?
Vision Techconnect V2 XLR Male Module
or
VISION TECHCONNECT MODULE FEMALE XLR - TC-XLRF
4: Any suggestions or ideas?
I should add that my PC does leak to ground, it is a PC, they all do.
My CDP also leaks to ground, no friking idea why, but cannot afford to get it fixed, it is a small trickle like the PC, but disconencted the case charges up (that may fix the loop, but there are problems eg electrocuted cats. )
