Hi,
I've had a 2017 Brio for a couple of months now and have been very pleased with the sound quality so far, however all is not well.
The first issue became apparent within a couple of days. On switching the unit on, there were two or three occasions where no sound could be heard coming from the unit and it was necessary to power the unit off and on again for it to start working properly. This seemed to resolve itself after a week or so of operation so I decided to ignore it and hope it didn't repeat itself.
Today I used the headphone jack and with no signal present immediately noticed a low hum coming from the right earpiece. I unplugged the headphones and placed my ear next to the right speaker and sure enough the hum was present. It is also present in the left speaker but is not as loud. I noted that:
The hum is present on all inputs.
The hum is present when there are no inputs connected.
The hum seems fixed and does not change with changes in volume.
As well as the hum mentioned above, there is also a distinct hiss that appears when input 1 is selected and the volume dial is set at 11 o clock or higher.
I normally only use input 2 with a DAC.
I have tried unplugging everything from the AMP and relocating to another room, then plugging only the headphone into the amp but the hum is still present.
Should I be looking to return the unit? Having googled around (even before I bought it) it was apparent that others have had problems with unwanted 'hum' from various iterations of the Brio. |
