I saw these featured on Innerfidelity and they got me intrigued with their current drive technology which is completely new to me.
As I understand it though these type of amps treat output impedance differently to traditional voltage amps and they can " adapt " (for want of a better word) to drive any headphone from 8 to 600 ohms without affecting the frequency range.
To me this sounds very interesting as it would be very versatile in driving anything from IEM's up to the hard to drive 600ohm headphones.
Does anyone know much about this technology ? is it new to headphone amps and how do they compare sonically to the voltage drive amps ?
