Update to anyone having the same problem as myself. I had to get the unit replaced. New one is good and working as expected.

(Noisy Amp, but sounds great with Diana and 1266

Yup sounds good with abyss. The noise right is due to the charger. Use it purely on battery. Is the best. Alternatively getting a better charger does reduce the noise. I never tried with a good linear power supply like the hypsos, but with a better Switching power supply, it gets significantly quieter

Interestingly… switched from Mojo as source to My Cayin N30LE DAP with LO and the noise is almost gone now. Clearly I need a better DAC as well.

How is Formula S compared to Broadway in background noise?

the noise may not be amplifier self noise and may be more of a grounding issue as it disappears when the wall wart is disconnected

Just got a K Dac in form a forum member, but no remote was included. Is there a way to change the filters without the remote?

Never mind I just figured it out… lol
