K-03X Humming Noise

[GreginNH1]

Hi all,

I was wondering if any K-03X owners can chime in on this issue.

When the unit is turned on, there is a constant low-level hum. I should note that this is without my amp being turned on!

Any feedback would be greatly appreciated.

Just to clarify, is the hum you're hearing audible from the K-03X itself and not through the speakers? I would assume so since you stated the amp isn't on but wanted to be sure.

No hum through speakers. Only from K-03X

Greg.
Although not the same component, when I got my new Krell amp, there was a audible hum when unit was on and less so when off.

The hum disappeared after a week or so of continuous playing.
May just be nothing more than a new unit burning in.

I do not have a hum. I do hear a soft whirring noise when a CD is spinning, and have read posts from others about same noise.

Any issue loading cds in the tray or ejecting them?

None at all. Smooth as butta (as they say in New England)!

I have had a faint spinning noise from all Esoteric gear from DV-50s, P-0s, UX-1, UX-1 Limited, P-03U (more pronounced) and P-02 though SACD bring out more as it is a higher speed spin to begin width but it's never audible more than 1-2" from the units, the P-03U a bit more (5-6"). Again, extremely faint and never heard at the listening position. There were issues many, and I do mean many years ago with bearings in a specific transport version but Esoteric resolved those.

More specific to your issue,...I've never had any kind of hum though from any Esoteric unit. Do you have the unit into a power conditioner or straight into the wall? Try reversing it one way or the other. This is a strange issue and almost plays like a bit of DC noise on the line aggravating the power supply or a grounding issue but I would think you would hear it from the rest of your gear as well. Let it burn in a couple of days as it could be to another poster's reply as something that just needs a bit of burn-in for the power supply to get past.
