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.

Thanks @elliottbnewcombjr 

Yes, I have switched back to RCA, and things work as designed. It’s an “OK” solution, as I purchased and paid extra for, these two pieces so that I could connect them in balanced fashion.

I’ve reached out to ROSE HIFI support, as the problem does appear to be on their end. Rather it be their electronics or connector.

How do I know cables are good, I purchased a cable tester from Amazon.  Love it!  Highly recommended piece of kit for tinkering audiophiles.  See link.

Yes an xlr cable can cause low volume I just had a similar issue I had to turn my dac all the way up and amps up to hear almost anything. I troubleshoot by disconnecting xlr from everything and tried each amp individually they all worked fine so the last xlr was causing the issue when I connected it the sound went low again. I than tested the cable and the ground signal has an issues I redid both sides and fixed the cable and sound returned to normal. A tip for plug-in xlr there is usually a click that lets you know if you don’t hear a click it’s not connected properly.
