Know before you buy
The BerTTi stands out by incorporating Chord Electronics' proprietary ULTIMA technology, which uses advanced error-correction circuitry to provide significantly higher precision and lower distortion than standard designs.
With 75 watts per channel into 8 ohms, the BerTTi is designed primarily for high-quality desktop or bookshelf speaker setups. While it offers excellent clarity, it may not have the headroom required for very large, power-hungry floor-standing speakers in a large room.
No, the BerTTi is a dedicated power amplifier. It does not feature a built-in DAC or volume control, so you will need to pair it with a separate preamplifier or a DAC that includes a variable output.
No, the BerTTi is not bridgeable. It is designed as a dedicated stereo power amplifier and cannot be combined into a mono configuration.
The amplifier is highly versatile, featuring both balanced XLR and unbalanced RCA inputs, allowing it to integrate easily with a wide range of preamplifiers and source components.
The BerTTi is very compact, measuring 235mm wide by 256mm deep. Its small footprint makes it an ideal choice for desktop audio systems or tight shelving where space is at a premium.
