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 take on the brand
Imagine a sleek, compact design that oozes class. Imagine an amplifier design that packs enough power to comfortably handle even the most demanding of loudspeakers. Imagine a complex yet agile and easy to use fully transparent line stage. Imagine every possible Phono EQ setting available from the comfort of your listening chair. Imagine a highly acclaimed discrete DAC boasting the best specs and sound around. Imagine, combining all of the above!
Reality. Is. Kula!
Kula is an a la carte modular design creating a fusion of highly technical previous accomplishments. The chassis itself is borrowed from the acclaimed Makua preamp, as is the line stage section and its optional phono stage with independent adjustable settings and up to 6 separate inputs. The optional DAC section which also is available in the Makua, is identical to the world-class Tambaqui stand-alone unit and features 5 digital inputs including Roon endpoint and Bluetooth.
Additionally, the Kula incorporates a Mola Mola exclusive amplifier which boast an output of 150 Watts @8 Ohm, doubling into 300 Watts @4 Ohm. Clearly enough power to drive any speaker with ease.
Our summary
Product Strengths
- Exceptional audio quality from its line inputs, optional streaming DAC, and optional Phono stage
- Stunning transparency, commendable focus, and open and airy sound staging
- Inspired and seamless reproduction—with a spark of life quality
- User-configurable phono stage that competes with pricey dedicated boxes
- The DAC module, based on the Tambaqui, rivals many uber-expensive standalone units
Product Considerations
- The Kula gets quite hot during operation, needing a decent amount of ventilation
- The LEDs are very bright, and there is no way of turning them off
- The remote is borrowed from Apple TV and is not refined enough to give decent control over volume
- There is no coaxial digital input
Comparisons (according to reviewers)
- The Kula sounds a little sweeter than Mola Mola Kaluga mono amplifiers
- The Mola Mola Kula sounded like a sibling to Leben CS600
Takeaway: The Mola Mola Kula is a state-of-the-art, all-in-one amplification solution that brings music to life with transparent and life-sized sound. With optional modules, it becomes a highly versatile and elegant solution for audiophiles who want top performance in a single box.

Our take on the brand
Our Summary
Product Strengths
- Unique and eye-catching 'steampunk-inspired' industrial design stands out from typical amplifiers and could be considered a work of art
- Offers a versatile feature set, including a customizable phono stage (MM/MC), bass and treble tone controls, and a defeatable active crossover for bi-amping
- Delivers a transparent, detailed, and generally smooth sound, described as not sterile, analytical, or dry
- Multiple amplifier configurations are available, including BTL mode for increased power (400Wpc), accommodating various speaker setups
- Uses GaN FETs which the manufacturer claims improve sound relative to traditional Class D amplifier designs
Product Considerations
- The 'Class D' or 'Class AD' amplifier topology might be a concern for some audiophiles who prefer Class A or AB amplifiers and associate them with better sound
- Some reviewers indicate a preference for the sound of Class A/B amplifiers over the RA180, particularly in bass weight
- The remote control is IR-based and requires a separate receiver 'nubbin' to be plugged in
- A small audible noise floor was practically non-existent in "normal" mode, but heard with some speakers in BTL mode
Comparisons (according to reviewers)
- The Michi X3 is preferred overall, though the RA180 has superior build quality and phono stage, and the X3 also has more bass weight
- The RA180's midrange and treble performance is compared favorably to the NAD M33
- The McIntosh 7200 has true Class AB topology compared to HiFi Rose, though the HiFi Rose is preferred in smaller stature and industrial design
- The RA180 bests the Pass Labs XA 60.8 and XP-22 in low-volume late-night listening
- The Enleum AMP 23R had lit up treble, but the RA180's treble was forward—but not bright—energy
Takeaway: The HiFi Rose RA180 is a unique and powerful amplifier that sounds great and offers many ways to set it up to get the best sound. It is a showpiece that is sure to spark conversation.
