Headphone Reviews and Discussion - Head-Fi.org

I've been beating the drum for the Micro iUSB3.0 for a long time! Welcome to the club. Now go out and buy one!

Thank you for the very interesting review, as I am new to the DAC/Amp/filter scene, could you help me understand how this works?
I thought a USB port just forwards the ones and zeros from the music file to the DAC, which transforms the sound into a analogue signal. The analogue signal is where the distortion etc is formed from interference.
In HDMI cables for example, I've never seen any difference in image quality switching from a $4 and a $180 cable.
How can a binary data stream be cleaned up while it only contains the data from the original music file?
Thank you for you help.

I can't pretend to understand all the tech behind it but the difference is audible, and I did a check for volume effects in my iPurifier2 review, but iFi has some good explanation on their website. They also are very good about answering questions, so I'd shoot their support team an email. Here's the link:
