TToby Solid State Amplifier by Chord Electronics

The TToby stereo amplifier, in combination with Chord’s 1M-tap M Scaler upscaling device, and the Hugo TT 2 DAC provides a complete high-quality hi-fi system, with desktop dimensions and a space-saving footprint. Despite its size, the TToby sets new standards for small amplifiers and takes full advantage of Chord Electronics’ proprietary amplification technology and design know-how.

The addition of TToby, enables owners of the Hugo TT 2 to fully exploit the device as a ‘digital preamp’, effortlessly driving a wide variety of loudspeakers, large or small, in addition to the Hugo TT 2’s headphone prowess. The TToby is a 100-watt design, featuring both an unbalanced and balanced input, to take advantage of the Hugo TT 2’s XLR output.

TToby features two of Chord’s famous high-frequency power supplies and benefits from forced air-cooling through the aluminum casework by means of a sonically closed anechoic miniature multi-speed quadruple-fan plenum chamber, enabling the external design to be free of sharp heatsinks and, therefore, carry a stunning aesthetic. The M Scaler – Hugo TT 2 – TToby combination offers both class-leading DAC and amplification technology via headphones and loudspeakers, giving complete flexibility for the most demanding audiophiles.

“The TToby surprised us. We weren’t expecting such a balanced and musical performance from something so compact. It just goes to show that everything should only be judged after listening. Despite appearances, this is one of the finest power amps available for the money.”

“The Chord Ttoby is fully balanced and has an ingenious mosfet power amplifier on board. Eight capacitors should do covers things nicely and with a frequency range of 5Hz -100Khz and a distortion of only 0.0016% the specs look promising. ”
