Sonoma Acoustics Model One Electrostatic Headphone System
The complete system includes:
Model One (M1) electrostatic headphones - With injected magnesium ear-cups, handmade Cabretta hair sheep leather (on ears and headband), and a custom low-capacitance cable created in collaboration with Straight Wire Inc.
Class-A Energizing Amplifier - A discrete FET Class-A amplifier, ESS SABRE 32-bit Reference DAC, custom 64-bit double-precision fixed-point DSP, 32-bit/384 kHz AKM Premium ADC, universal voltage switch mode, in a machined aluminum enclosure. The USB input accepts all Hi-Res Audio formats up to 32-bit/384 kHz PCM and DSD via DoP (DSD64 and DSD128) and the S/PDIF input accepts all PCM formats to 24-bit/192 kHz. The Model One system ($5,000) can only function as, and be purchased as, a whole system.
I enjoyed what I heard at CanJam, though I was surprised by how far I had to turn it up to get any sound. And while I understand the need for the two to be sold as a pair, it may seem restrictive. I wonder how headphone enthusiasts will react once the M1 System is out on the market.
In this video, Sonoma Acoustics GM David Kawakami gives a nice run down of the M1 system:
