What reviewers think
Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.
Product Strengths
- Very powerful, with 300 watts per channel, the I-180 is capable of driving almost any loudspeaker with ease and keeping speakers under control
- Reviewers highlight a naturalness to vocals and instruments, and a blackness behind the music that allows for hearing more micro details and information
- The I-180 renders a very weighty and captivating sound, with a pitch-specific, extended-sounding bass and extremely quick transients
- The amplifier is able to produce music in a more relaxed manner with very detailed sound that never sounds etched or overly detailed
- The UMAC amplifier technology surpasses the sound quality of other recent Class D amplifiers with sine-wave modulation instead of triangle modulation PWM
Product Considerations
- The Apple remote does not add to the intangibles that often improve the user experience
- The amplifier needs time to warm up, around 20 minutes until it reaches 35 degrees Celsius, before it sounds its best, sounding 'dry and almost lifeless' before reaching operating temperature
- Some found the sound to be not immediately impressive, requiring extended listening to fully appreciate its qualities
- The unit only uses RCA sockets
Comparisons (according to reviewers)
- Vs McIntosh MA252: The Aavik I-180 had a naturalness to vocals and instruments, and a blackness behind the music
Takeaway: The Aavik I-180 is a capable amplifier that delivers clean and detailed sound and is able to drive demanding speakers. With its ability to remove background noise and produce a more relaxed sound, the Aavik I-180 is great for longer listening sessions

Our take on the brand
Used
Aavik
What if you spend a bit more?
The Aavik U-280 Unity amplifier is processing the digital signal to an almost limitless soundstage and with plenty of power ressources. The music is presented on a huge black background.
Our Summary
Product Strengths
- Superb, magnificent, and powerful sound with an enormous soundstage
- Aavik components are known for their noise reduction technology, employing Tesla Coils and analog dithering
- Known for a low noise floor, resulting in more musical detail and razor-sharp transient images
Product Considerations
- One reviewer would like the ability to rename the sources, to match the connected devices
- The U-180 can be a little dull or muted with some speakers, and is not the sunniest or most emotionally engaging performer
- Some reviewers found the Aavik components sound a bit dark
- Class D circuitry is used, however Aavik has developed the UMAC amplifier to avoid some of the shortcomings of switching amps
Comparisons (according to reviewers)
- The U-280's internal DAC was not embarrassed by the EMM Labs converter, and produced a fantastic sound, even when streaming a 'CD quality' source
- The U-280 sounds considerably smoother and richer, more fluid, organic, and refined—and it is also markedly sunnier
Takeaway: The Aavik offers a powerful and refined audio experience thanks to its innovative technology. It's a keeper, especially if you like listening to music with great clarity.

Our take on the brand
Our Summary
Product Strengths
- Potent, solid, and full-sounding, with excellent resolution and a great built-in DAC.
- Considerably smoother and richer, more fluid, organic, and refined than the U-180, with a significantly deeper soundstage and more 3D imaging.
- Adds a welcome amount of treble air and openness, with a considerably more neutral presentation than the other two models, while maintaining warmth and fullness
- All models have a built-in DAC that is of very good quality
- The amplifiers offer multiple connection methods (USB, S/PDIF over BNC) allowing the owner to choose the format that works best in any given situation
Product Considerations
- Can sound a little dull or muted with some speakers and is not the sunniest or emotionally most engaging performer, its darker tonality might cover up the instrument's true tonality
- Stacking the units can affect their sound, with the bottom position making the sound heavier and darker
- The non-metal enclosure may not be ideal
- The U-180 and U-280 have a slightly dark and 'wooden' tonality, which can be a detractor
Comparisons (according to reviewers)
- The U-280 is smoother, richer, more fluid, organic, refined, and sunnier, with a deeper soundstage and more 3D imaging
- The U-580 adds more treble air and openness, with a more neutral presentation
Takeaway: Aavik amplifiers are potent and full-sounding with a great built-in DAC. The U-280 and U-580 models build upon the strengths of the U-180 with improved refinement and soundstage

Our take on the brand

The ULTIMA INTEGRATED is a class-leading 125-watt integrated amplifier benefitting from the latest dual-feed-forward error-correction topology, Chord Electronics' legendary proprietary ultra-high-frequency power supplies, plus an unmistakable industrial aesthetic.
Designed by Chord Electronics' founder, owner and chief engineer, John Franks, the advanced ULTIMA circuit monitors and immediately corrects audio signals before the output stage, for astonishing signal accuracy from a one-box integrated device. The ULTIMA INTEGRATED also takes advantage of the very latest developments in advanced low-distortion power supplies – devices offering exceptionally low noise and outstanding amplifier operation – for even greater fidelity.
A four-input design, one fully balanced and three unbalanced, all enjoy individual buffering and are selectively filtered against potential ingress from radio frequency interference; selection switching is via microprocessor-controlled sealed relays.
The ULTIMA INTEGRATED is the first new Chord Electronics integrated amplifier for seven years and remains the sole full-width integrated model in the range. All metalwork is precision-machined from solid aircraft-grade aluminium, including Chord Electronics' iconic Integra Legs. The fascia sports a 28-mm-thick front panel with a perfectly symmetrical aesthetic, centered around a spherical power on/off control with polychromatic lighting, flanked by illuminated volume and balance controls.
Our Summary
