Any experience with iFi Audio iDefender 3.0?

Break the noisy USB power, but in the correct way

 

There are more than a few products that break the USB power connection, but of the ones known to us, they do very little because the noisy ground connection remains.

 

For DACs that do not use USB power (except for handshake) the iDefender3.0® breaks the ground connection eliminating earth loops, while allowing normal handshake operation to continue. So in terms of cutting out the noise, it does it in the most comprehensive way possible while at the same time, in an electrically correct way.

I have an Aurender X100 connected to my AMR DP-777 SE via a TOTALDAC USB cable. Was curious about the effects and even though jitterbug was a total disappointment in my setup I decided do try this no brainer and return if it shows no effect.

 

But, complete opposite, improvement is clearly audible, bass is crispier and more precise. Did several A/B tests with different music genres, all showed an enhanced music stage. I will definitely keep it.

Is your dac using the usb 5v not only for the handshake..? I would like to try on my system.

I have no issues with ground loops using my phone but the 5V port is handy as I am bypassing the phone to get clean 5v battery regulated. If your dac can run without 5v Sbooster may be better. I need to run in new headphones before doing some more experiments..The I silencer is in the growing chain with a purifier 2. but it's pc based connections not phone so I have ordered gender adapters so it will fit in the intona pre dac. A lot of toys and messing around but I will post after doing some removing adding experiments when the headphones are sonically stable if I can perceive any benefits to all this spending.

An email to AMR would help you as it's thier companies..

Good luck

AMR doesn't need USB 5v, but it seems an improvement if the 5v output of the aurender is eliminated.

I see they have the USB iSliencer too, what's the difference?

[Middy]

The silencer has EMI RFI filter and thier reclocking inverse signal filtering.

Supposedly like the Jitter bug with an accumulation of benefit on the same USB bus. I got both to see if there is a benefit...Like I said I am still waiting for my headphones to settle and I had to buy two adapters so I can use it with my phone , not hanging out a laptop PC...

I need more time to judge..

Have fun
