Know before you buy
This advanced topology allows the amplifier to monitor and correct signal errors in real-time. By comparing the input and output signals, it significantly reduces distortion and ensures the audio remains as accurate to the original recording as possible.
While the BerTTi is designed to pair seamlessly with the Hugo TT 2, it is a versatile power amplifier that works with any high-quality preamplifier. It features both balanced XLR and unbalanced RCA inputs to accommodate a wide range of source components.
The 75W per channel into 8 ohms is quite capable for most bookshelf and medium-sized floor-standing speakers. However, if you have particularly power-hungry or low-sensitivity speakers, you may want to ensure they fall within the amplifier's optimal operating range.
The BerTTi is equipped with high-quality gold-plated speaker terminals that are designed for use with standard banana plugs. This ensures a secure, low-resistance connection for optimal signal transfer.
Despite its compact footprint, the BerTTi utilizes a sophisticated high-frequency switch-mode power supply, which allows it to deliver high-fidelity performance without the need for a massive, heavy chassis. Its precision-engineered aircraft-grade aluminum casing also provides excellent thermal management and vibration resistance.
Like most high-end audio components, the BerTTi will perform at its absolute best after a short period of regular use. You can expect the sound to settle and open up slightly after the first few dozen hours of operation.
