Will this unit stop a ground loop hum I am getting when I connect two seperate headphone amps to the same DAC?

It's possible that it will. You may have to move it to different devices to get the best results. First try lifting the ground of one of the amps with a "three prong" adapter. Maintain the AC ground on the DAC. Identical interconnect cables may help as well.

Before you buy you might post this question on the PS Audio forum. The designer of the DirectStream DAC, Ted Smith, will likely be able to answer your question. Your amps' grounds are at differing potentials and I am thinking that the transformer is not going to help. Using the balanced and unbalanced together breaks the "balanced" aspect of the line but the ground loop is a different animal.

umm I never tried 2 headphone in the same port -- It might work, but then the signal might be lower since its running 2 headphones on the same volume control

I connected two amps to it and it could not handle it. Go with a better eq. Clarion EQS746 1/2 DIN Graphic Equalizer with Built-in Crossover this is a better option.

we are not using it to power audio equipment so i do not know if it will produce a hum in your equipment the unit itself is quiet I know some supplies do hum but the one we have is quiet

Could be cable / power point issue..the XLR cable will cut off the hum..( Balanced cable )..

I am not fan a amp dac combo in a same box but i read for this tube amp/dac combo yes you should not problem but i recommend you try audioquest cinnamom usb cable you see a huge sound difference

I'm not sure of the design details but suspect the low power setting has a smoother sine wave output so won't cause "hum" in audio when used to power audio devices. Aybe somebody else as looked into the design in detail.

Make sure all of your equipment is properly connected. Do not use a device that removes the ground on power cords. I had a computer power supply plugged in with a ground eliminating adapter and it created a lot of buzz. I set the volume, treble, and bass all to 12:00 on the speakers.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

I'm no expert, love how my pair is performing. To answer your question, I would assume that depends on the other components in your system, especially the amplifier you're hooking them up to. Hope somebody smarter than me can give you a better answer.

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too.Maria

It's should be, the noise is usually caused by different components being grounded to different areas. This should eliminate the feedback loop you are hearing.

Yes,hook up one connection at a time and use the one that sounds the best.the other end leave disconnected.works for both 75ohms and 300ohms.

I've successfully plugged both into a power source without humming. However, I suspect it may vary from power source to power source, and maybe even from unit to unit. Your milage, it might vary.

i know i'm late to the party but if the inputs are parallel then you do not want to do this as there is the chance you could damage one input device as the other on tries to drive it. The test would be is there an output signal present on the rca plugs when the mp3 is in use? If not you should be fine. Hondo

I doubt it. Ground Loop Isolators do what they are called, isolate ground loops. Take for example when you plug your phone into the 3.5mm aux and you get music playing clearly. When you also have the phone charging at the same time, it creates a lot of noise. The ground loop isolator works to get rid of that issue. In your case, there would be no point in isolating the microphone unless it is a powered microphone.

Maybe, it depends on what you mean by 'crazy noise'. In my case, I was playing my computer through a receiver/amp and it started off ok but then there was a feedback hum that go louder. I put this between the two (without connecting the other 'curly wires' and it was perfect. For prox $12 why not give it a try, if it fails it might wind up being useful in the future.
