Can a poorly connected XLR connection cause a reduced(less loud) signal?


Been chasing a gremlin. I have an XLR balanced connection between a ROSE HIFI 150b DAC/streamer and an Accuphase E-380 Integrated Amp.

I have noticed the left channel to be a bit quieter, less bright, and measuring a bit lower on the Accuphase’s DB meters. The problem has been intermittent. I feel like I may have solved it, albeit temporarily, by pushing the XLR farther into the connector on the ROSE HIFI. I had read on their forum site that those connectors could be problematic.

But the basis of my question is: Can a poor XLR/balanced connection result in a lower/softer sound?

I have experimented with switching the cable, and even bought a different cable, don’t believe it to be a cable issue.

 

Edit: yes, I know my post title is a grammatical nightmare.

I think I have experienced this issue before. XLR's sometimes do not have a very robust grip. On suspect connections I have wrapped the XLR's with tape with extra length attached to top of amp to act a sort of "hoist" that pulls the connector upwards thus reducing sag. This is a commonly known technique for improving the connection of power cable plugs too.

Thanks for all the responses.  I have tried multiple new cables, but have also ordered a cable tester, and tomorrow will be able to know for sure about cable.  I have seen other posts on the ROSE HIFI forum that these connectors could be problematic. I have entered a support ticket on that forum. Will let you know what I hear.

 

@elliottbnewcombjr was your issue on Rose HiFi gear, or something else?
