What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- The T+A Cala CDR is a compact all-in-one system with both flexibility and performance
- A broad range of connection options including FM radio, DAB+ receiver, wi-fi, digital and analog inputs, USB ports, and a LAN socket
- The amplifier provides enough power to increase the volume, with a stable 100 watts per channel
- Sounds elegant yet powerful and can coax unspectacular loudspeakers into demonstrating qualities
- Minimalist design and comes in black or silver aluminum housing, as well as green, blue, red, or white ambient lighting, making it an understated eye-catcher that would fit on practically any shelf and look good with any interior decor
Product Considerations
- The rear panel headphone socket is less convenient than a front-panel output
- The LED lighting built into the lower section of the rear panel is very bright and more than capable of illuminating the room, meaning it's attention-grabbing on first encounter and quickly somewhat distracting
- The app is easy to use and allows one to operate almost all the available functions, it does occasionally fall short in terms of transmitting commands to the CALA, though
- With everything 'flat' the balance is seemingly tailored to make music easy to enjoy at the risk of slight anonymity, and even turning the 'presence' and treble up a bit fails to shoot the sound through with sufficient vitality and bite
- Some instrumental timbres can sound a little over-polished
Comparisons (according to reviewers)
- Versus the Technics SU-C550, it offers a similar specification, but in a very different design, complete with a top-mounted CD transport
- Versus the AVM Inspiration CS2.2, it is the same kind of concept as the T+A, and, like the Cala CDR, is handbuilt in Germany, but the major gain here is in power, the relatively compact casework containing amplification able to deliver a hefty 165W per channel
Takeaway: The T+A Cala CDR is a flexible and elegant all-in-one system that combines multiple functions into one device with good sound quality. If one is looking for an outstanding streaming server, receiver, amplifier, and CD player all rolled into one, this could be a great option.

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- T+A leverages a high-voltage (HV) power supply to achieve a tube-like response from solid-state components, increasing the voltage rail to 100 volts compared to the typical +/-16 to 24 volts.
- They employ a proprietary "True 1-bit" DSD converter, processing DSD data in its native bitstream form, rather than converting it to PCM, in select DACs and players.
- T+A incorporates in-house designed switching power supplies over off-the-shelf components, maximizing current delivery and improving sonic payoff.

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.
Product Strengths
- Astonishing agility, precision, and clarity
- Spacious and uncluttered presentation
- Sturdy build
- Combines the precision and speed of older designs, but renders the sound with a naturalness
- Provides plenty of power without compromising on detail or clarity
Product Considerations
- Most rivals are better equipped
- Can sound thin if partnered poorly
- Could deliver stronger dynamic contrasts
- The balance control has no center detent or marked position
- No digital inputs or Wi-Fi
Comparisons (according to reviewers)
- Vs Mark Levinson's No.5805 or PMC Cor, some may prefer the warmer, fuller presentation of rivals
- Vs Naim Supernait 3, it doesn't track the music's rhythms with the skill of the Naim
- Vs Rega Elex-R Mk3, the Chord Ultima Integrated delivered undeniably elevated sound in all respects
- Vs Bryston 7B 3 monoblocks, midrange, especially with vocals, was more lifelike through the Ultima Integrated—smoother and more liquid
- Clear preference for Chord Ultima, especially the dynamics
- Vs Accuphase E-270, the Chord is more natural and closer to the CH Precision system in terms of tonality and neutrality
Takeaway: The Ultima Integrated offers much of the performance of Chord's pre/powers in a neat one-box solution, presenting a refreshingly straightforward product to use. The Chord Ultima Integrated is a thrilling and soothing amplifier capable of weaving a wonderfully spellbinding sound.

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.

- 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.
