I bet your average dude on the street can’t name a single audio company that’s not in the headphone biz now. For an audiophile, it’s easier. As I look around my listening room, I see lots of them: AudioControl, Canare, Hsu Research, Krell, Rotel, Sunfire, and Sonus Faber, none of which have (yet) entered the personal audio field. But that’s changing. The Pro-Ject RM-1.3 turntable sitting atop my audio rack now shares its brand with two headphones, the $129 Hear It One and the $79 Hear It Two.
