I bought a couple of Humbusters to try and get rid of my subwoofer hum.
You are welcome to try them to see if they would help.

Don't want to mislead anyone. The Aurieges was returned only once due to hum to one of the speakers. The other return was for a used defective Shindo IC.

Thank you for the offer. Could you post some links to the device?

An idea would be to give up the Auriege option for your preamp and try an other Shindo preamp.
There might be a problem with your electric installation. Matt surely tried it in his place before sending the Auriege back to you. I suppose that you tried to plug the preamp in other places of the home ? Do you have this transfo hum while nothing is connected to the Auriege ?
Well, at least, you probably have one of the best audio dealer in the US so you will be treated beyond expectations.
Relax ! You're in good hands.

Matt has been awesome. I feel bad emailing him with all my problems.

I will try to disconnect all cables to see if hum persists. The weird thing is, the hum was only slightly audible at 2 feet before I got the Mr. T. Actually, I've never noticed it for the past 2 months since I got the Aurieges. It happened when the Mr. Ts. arrived.

I unplugged the Mr. T. from the outlet and plugged the Aurieges direct into a different outlet. Same hum. I think the hum is amplified by my cabinet too. When I lift the Aurieges slight, hum decreases.

The Shindo power cords are 2 prongs. I did reverse the plugs with same result.

Tried the Aurieges on another outlet, same result.

The Mr. Ts. hum very slightly. I don't expect a huge transformer to be dead silent. I'm OK with that.
