Hi

I received today a SD1000 and it produces less sound than SD2 however it makes much more humm noise when it's not playing any sound is this normal? What is your experience?

Thanks

Hi,
i have no SD2!

My SD1000 does not hum! The sound is without any hum or noise. The SD1000 goes into an Wersi Spectra as AMP.

Check your ground connection (shield from the shielded cable) to the AMP!

Is it USB powered, or do you use the external power supply?
You can try it with headphones too
I have no noises or humming too with my SD1000
