  • $ 3,695

TToby complements Chord's desktop DAC / headphone amplifier, 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, 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 Hugo TT to fully exploit the device as a digital preamp, effortlessly driving a wide variety of loudspeakers, large or small, in addition to Hugo TT’s headphone prowess. TToby is a 100-watt design, featuring both an unbalanced and balanced input, to take advantage of Hugo TT’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 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.
