Beyerdynamic I almost missed the small Beyerdynamic booth, which had some lovely, understated, and decidedly European-looking headphones. The T 1 ($1,295), with its gray on gray coloring is subdued in that typically German way. This was actually my next stop after the Boomphones booth, so it was nearly culture shock, given the lack of red LEDs and "working my way through college" booth babes. I'd also be willing to bet that Technical Support Manager Gunter Weidemann, who showed me around the booth, has never said "Dude" in his life. Gunter mentioned that even though the T1s were rated at an extremely high 600 ohm impedance, they can be run by any headphone amp. A 102 dB SPL is possible, as is a claimed 5 Hz to 50 kHz frequency response. They were light and comfortable and sounded excellent.
Beyerdynamic's A 1 headphone amp ($891.45) is made to power any of their headphones, and has a claimed frequency response of 1 Hz to 100 kHz (-1 db) and can put 100 mW into the 600 ohms of the T 1s, or 150 mW into 30 ohm headphones. north-america.beyerdynamic.com
