Operational Specifications for the Black AMP
1 – Output Drive
The Black AMP is a current mode amplification process. Instead of the typical artificial ‘zero’ impedance output of feedback based amplifiers, the Black Amp output is high impedance. This is a current source driving the headphone transducer in a more ‘natural’ process, the result of no global or stage feedback.
2 – Noise
Signal to noise is over 115 dB (weighted, that is 60 Hz limited) from a 2 volt RMS output. Noise is one of the important factors that limits resolution and the details needed for a true soundscape. The Black AMP’s unique clarity and resolution is rooted in noise between the spectral elements of the musical signal.
3 – Distortion
4 – Square Waves
Square-waves reveal both stability and bandwidth issues. Without resorting to using feedback, the Black AMP is flat and stable out to a megahertz assuring no interactions and odd-harmonic artifacts to reduce resolution and musicality. In technical terms, the Black Amp behaves flawlessly through and past the audio band.
How does this technical data equate to sonic performance?
1 – The data shows that the dynamic nature of the amplifier does not change with frequency, and that frequency range far exceeds that of the audio spectrum. A change in distortion based on frequency says that the amplifier is essentially a different amplifier at each frequency. This means that overtones or harmonics for any specific instrument being reproduced are diffent when amplifed in such a topology.
The amplifier is the same source to the transduceres at all frequecies. Damping , distortion, gain, all remain the same when seen by the speaker or headphone.
This performance consistancy is the key to timbre-fidelity and spacial coherancey, the better sonic image, the eargasm.
