Seeing as we are off topic I will add a note about Ken. He does get a bad rap from many of the HC fanboys, mostly over his cable philosophy and his early vocalization thereof. Jenna gets the same label. I will not get into the cable debate, I am not a zipcord supporter but neither am I a fan of other extreme. I am however very fond of Ken and his approach to this hobby and his support for his customers. I also don't care that he charges what he does for his cables. He does everything himself and braids those cables one at a time. For those who have tried to make cables of this sort will understand the HUGE pia that is and how easy it is to screw it up. Every hour he spends making those cables instead of spending time with his wife and young child are very valuable and come with a price. As for his amps and other components, he is not an amp designer and relies on people to collaborate with him to build any product that he brings to market. They can only be as good as the people he chooses to work with. I think he has generally chosen well.

My approach to portable amps is akin to headphone world toys. I generally have not taken them very seriously as I do not listen seriously when on the move. The govibe makes music on the move sound a lot better than the overhead noise and i have shifted to using headphones that work well without an amp to make it even simpler. I would probably feel differently if I used a set of UE reference ..dB
