I have a Hifiman toxic cable on loan and simply put the build quality is amazing as well as the customer service. It's my understanding this is a one man show and the response from my many questions has been fast and very professional. Considering the number of orders for one person it is pretty amazing. The quality of the cable and Frank's service convinced me to buy a Hifiman cable for my HE6 as well as a cable for my JH5 customs. The prices are great when you see what you get for your money and certainly looks like it should be much more expensive.
May I Ask which one u have as a loan? As i have a he500 myself and am curious..and how does it change the sound compared to standard cable?
