I bought this balanced cable so I could plug it into my Drop +THX AAA 789 Amplifier, but it's taking a really long time to arrive. So I bought a 3.5 mm jack adaptor to use it on other small amps. It sounds great. I'm not sure if it sounds much different but it allows you to have a fully balanced system set up for your headphones. I can't wait to use it on my 789!
