This means @jea48 is correct - you have a ground loop hum. I still had my hum with only speakers plugged into amp and no other components connected. You need to go through through a process of elimination adding one component at a time to see which is causing the hum.
Krell KAS amplifier hum
The amps are directly plugged into their own dedicated 20A outlet. Is there a "conditioner" I can use to minimize/eliminate the mechanical hum I'm hearing through my MBL 111f speakers. I'm not looking for a multiple outlet item, rather, one which plugs directly into the wall and into the back of each monoblock. Please advise and thank you in advance.

And a DC offset eliminator may not completely remove the mechanical hum from transformers. This has been my experience with one particular amp, and after trying everything possible the only culprit remaining was delamination "rattle" from loose windings over time. The DC offset measures helped but didn't fully eliminate my issue with the tube amp. Every other amp I've ever plugged into the same circuit, tubed or SS, never hummed a peep using the same speakers/system. Sometimes it's simply the amp and not DC riding on your line. |
@jg2077 This Emotiva CMX-2 at just $129 is a good starting point to see if DC offset can be removed. It comes with a 30-day return so not much risk. You will know right away. It my case it removed about 50% of the transformer hum. https://emotiva.com/products/cmx-2 |
