Cute Curve

"Cute Curve"- Class B - Push/Pull - Headphone Amplifier
This class B, Push/Pull Circuit amplifier is optimized for a wide range of load impedances and suitable for almost all headphones. This high bandwidth, extreme low noise design (lower than -104,7db) yields greater than 104,6 dB of dynamic range and exceeds the capabilities of the human ear, ensuring to handle any difficult headphone. The Cute Curve class B-Push/Pull design is offering extreme clear sound, but with much more power then a Class A amplifier. The Cute Curve is therefore more suitable for "music-lovers" (read non-analytical listeners), and people that need powerful sound with capability to feel the base (if you want). The Cute Curve serves best for musicians/studio-use/DJ's with (closed) headphones that need to be driven at adequate volume, due to high surrounding noise. However, do not understand wrongly : the Cute Curve is also perfect for the audiophile that just loves a bit more power.
