CEntrance's Tiny USB Headphone Amp
I was aware of CEntrance from the code they supply for the Texas Instruments USB receiver chip used by Benchmark , Bel Canto and others to allow USB connection without there having to be a driver program on the host PC. But the Chicago-based company also makes USB-based hardware, and at THE Show, Jason Serinus and I bumped into their Managing Director, Michael Goodman (left) who is showing Jason the cute DACport USB Headphone Amplifier ($500). This 24/96-capable, bus-powered, cigarette lighter-sized product has a miniature USB port on one end and a ¼" headphone jack on the other, with a small volume pot on top. CEntrance also makes similar bus-powered products with an A/D converter to connect microphones and electric guitars to a PC via USB.
