Ebtech Hum X

The Ebtech Hum X was recommended to me to eliminate ground noise from a USB DAC connected to an amplifier.  It works as well as a cheater plug, but does anyone know if it's actually safe(er)?

If it works the same as all of the DIY ground loop eliminators I see on YouTube then yes, it is safer (and ten times more expensive).

More expensive than the cheater or the DIY versions?  The DIY build looks like more than $5 worth of parts.

Under $10 including all the shipping charges? What vendor could do that?

A quick trip to Home Depot and Radio Shack should suffice.

I like how making multiple trips, to numerous vendors, gasoline, time spent on travel, parking [or in my case, public transportation], time waiting on line to buy parts, [which many Radio Shacks no longer have], and assembly time once you get home are all "free" and/or an inconsequential expenditure of time.

The Hum-X shipped for about $50 seems perfectly reasonable to me, but then again I'm the kind of guy who doesn't make my AC extension cords and patch cables from parts; I buy them.

Another possibility, if you don't mind modifying equipment and possibly voiding the warranty, is to open up the receiver and add the $2 in parts that will isolate its ground while maintaining its safety.

So, will I need a soldering gun?

You could, but wire nuts would probably work as well, if the connection from the AC ground to the chassis is a short wire that can be cut.
