Posted by The Sound Organisation on Aug 7th 2025
With the introduction of the BerTTi stereo power amplifier, Chord Electronics brings its legendary Ultima amplifier technology to the compact Table Top range—and it doesn’t just perform, it sings. Despite its playful name, the BerTTi is a highly capable and meticulously engineered component, crafted from aircraft-grade aluminum and designed to seamlessly pair with Chord’s Hugo TT2 and M Scaler for a top-tier desktop or rack-based system.
BerTTi is Chord’s most compact and affordable Ultima-technology amp to date, but don’t let its size fool you. Inside, it features custom MOSFETs, precision error correction, and an auxiliary power rail to ensure instantaneous dynamics, low distortion, and effortless control—even with demanding loudspeakers. It delivers 75 watts per channel into 8 ohms with authority and refinement.
This fully balanced amplifier handles everything from high-energy rock to ambient acoustic recordings with natural tonality, impeccable timing, and rich detail. Its bass is punchy and articulate, the midrange transparent and emotionally expressive, and the treble smooth yet revealing. Whether you're listening to CDs, streaming high-res audio, or spinning vinyl through a compatible preamp, BerTTi offers outstanding soundstage and pinpoint imaging.
Chord Electronics has built the BerTTi to prioritize sound quality above all else, keeping the interface simple and intuitive with just a power button and a clean rear panel of RCA and XLR inputs, speaker terminals, and a 12V trigger.
For those seeking world-class amplification in a compact footprint, BerTTi is a serious contender—not just within its price range, but among any amp that values musicality, dynamics, and a true-to-the-source presentation.
