A brief history of the product line
The original EarMen CH‑Amp quickly became a go‑to recommendation for hi‑fi enthusiasts looking for a transparent, neutral headphone amp with serious power under $1,000. It was designed as part of a modular desktop stack, often paired with EarMen’s Tradutto DAC, and it impressed with its ability to drive everything from sensitive in‑ear monitors to demanding planar‑magnetic headphones.
The CH‑Amp stood out with its composite amplifier design, ultra‑low noise floor, and CNC‑milled aluminum chassis. Audiophiles loved its sound signature: clean, dynamic, and true to the source.
The new CH‑Amp Signature takes the same core design and refines it further. The big difference? It’s now a complete all‑in‑one DAC, headphone amp, and preamp, adding features like:
A built‑in ESS9038 Hi‑Res DAC (32‑bit/768 kHz PCM and DSD)
Hi‑Res Bluetooth (aptX HD and Adaptive)
A bright OLED display with a VU meter
A rechargeable CNC‑machined aluminum remote
All while retaining the linear PSU‑3 external power supply and compact footprint.
