Chord TToby Power Amplifier

The TToby range may be ideally suited to compact living environments, but don’t let that fool you. With similar legendary amplification derived from our SPM range, TToby doesn’t compromise on power or providing you with the purest audio experience possible.


The TToby has been designed to complement our desktop DAC/headphone amplifier, the Hugo TT and shares the same compact form factor as its stablemate. The combination of Hugo TT and TToby provides a 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 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’s headphone prowess. The TToby is a 100-watt design, featuring both an unbalanced and balanced input, to take advantage of the Hugo TT’s XLR output.

TToby features two of our famous high-frequency power supplies and benefits from forced air-cooling through the aluminium 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 Hugo TT/TToby combination offers both class-leading DAC and amplification technology via headphones and loudspeakers, giving complete flexibility within the demands of busy households.
