I really like the TTVJ Portable, humorously dubbed the TTVJ Slim by a reviewer . I like the TTVJ form factor better because it is so close to the iPhone and iPod. Greg, the new TTVJ Portable is far better than the Hybrid for portable use and for IEMs. The three portable amps in the running for best JH|13 match are the TTVJ, the Pico Slim and the RX, but I have not yet managed to hear the damn RX. I will borrow JP's eventually but failed to compare them this weekend even though Vicki did so tonight in my room while we were all hanging out. She should post some comments if she has some to share, but they all appear to be good contenders.
