Frequency Response 5Hz – 50 kHz (-3dB) Output power 1000 mW + 1000 mW (60 ohm) Headphone impedance 16 ohm – 600 ohm Max. Input Voltage 2V(RMS) Inputs 1 pair RCA Outputs 1 x 1/4” TRS Power supply 30V/0.8A power adaptor Dimensions Net weight 850 g Follow the tradition of elemental amps, Sherlock is designed to be a no-compromise performer at very affordable price. We take a step further to make Sherlock expandable to be a fully balanced amplifier with unprecedented driving capability and musicality comparable to amplifier multiple of its cost. How we achieve the goal is to trim all the unnecessary feature and cosmetics, then focus on its core competence – the amplification. In the kernel of Sherlock is a class-A tube gain stage that dominates the sound quality with tube’s unique signature, followed by a single-ended class-A MOSFET power stage to provide plenty of current for whatever demanding headphones. What is unique in Sherlock is we add a bridged circuits in front of the main amp, when activated, which conveniently converts input signal into balanced (positive plus negative polarities) format and feed to left and right channels. It turns one Sherlock into a single channel balanced amp and two Sherlock amps into a truly stereo balanced amplifier.
