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
- Joyful sound signature with detailed output
- Can power a wide range of headphones, due to Ultima technology
- Compact design, stacks perfectly with the Qutest and Huei
- Employs trickle-down Ultima technology to allow delivery of enormous peak current outputs
- Solid build quality using CNC-milled aluminum casework and good heat dissipation
- Connectivity options include headphone and speaker outputs
Product Considerations
- No gain switch for the headphone output
- Default gain level a bit high for sensitive IEMs
- More power limitations with speakers than headphones—best for smaller, efficient speakers or nearfield listening
- Runs hot, requiring good ventilation
- The volume control feels a little wobbly and might be difficult to use in a very precise way, and there is some channel imbalance at very low volumes
Comparisons (according to reviewers)
- Qutest/Anni pairing justifies its price premium thanks to a more composed and insightful presentation that offers notably more low-end authority, dynamic punch and tonal richness
- Cyrus ONE HD is plusher, showing that Anni has strong niche appeal
- The iFi xDSD Gryphon has digital inputs and built-in DAC, while Anni can power speakers
Takeaway: The Chord Electronics Anni is a compact and well-built amplifier that delivers a joyful and detailed sound, making it a great addition to a desktop setup for headphone and nearfield speaker listening. Its use of trickle-down Ultima technology ensures high-quality performance in a small package, and its ability to stack with other Chord devices makes it a good choice for those already invested in the ecosystem.

The LM-845IA is a quality upgrade of the old LM-518 amplifier. It delivers twenty-two watts per channel. Single ended design, Pure Class A, Integrated Stereo Amplifier with 845 output power tubes. The rear-illuminated front panel meter is used to adjust the polarization of the tubes. The use of high quality components (Realcap capacitors, ALPS potentiometer) wired in the air for the most part is the guarantee of exemplary reliability. Its transformers output are of EI type, specially disigned for power supply.

Product Strengths
- Pellucid sound, rich tone, and textural detail are characteristic of a well-designed single-ended triode (SET) amplifier.
- Forceful and tuneful bass defies the stereotype of slow or puffy bass in SET amps.
- Expansive soundstage allows instruments and voices to float free of speakers.
- High build quality includes point-to-point wiring and quality components, such as an ALPS potentiometer and RealCap capacitors.
- Dynamic slam and a physically involving sound
Product Considerations
- The 845 tubes operate at high temperatures, potentially causing burns if touched and significantly increasing room temperature.
- No balance control
- Some found the stock tubes to impart an aggressive or steely tone that could be improved with tube rolling.
- Careful matching with speakers is required, one reviewer noted inexplicably harsh sound when paired with certain speakers.
Comparisons (according to reviewers)
- The LM-845IA has changes to internal components and redesigned output transformers, compared to the LM-518IA.
- The LM-845IA has a lighter touch and more refinement, while the Gold Note PA-10 monoblocks sound more solid in the bass.
- The LM-845iA offers a more powerful punch, while the Kora TB140 sounds lighter on its feet and faster.
- The Ayre EX-8 edges out the LM-845iA in clarity and detail.
- The Cambridge Audio Edge NQ sounds similar, but can't quite match the realism or the directness of the Line Magnetic.
Takeaway: The Line Magnetic LM-845IA is a powerful tube amplifier that offers a unique and engaging listening experience. It's a good choice for audiophiles who want a robust and resolving sound with dynamic contrasts.

Our take on the brand
Product Strengths
- Sweet sounding treble and expressive, emotional midrange
- Detailed across the board, and remarkably easy to listen to
- Strong rhythm, lively sound, excellent articulation, and a very good sense of being there
- Fast dynamics and good three dimensionality
- Voices and instruments are very naturally reproduced
- Connectivity options...
Product Considerations
- Fussy about speakers, ideally speakers should have a sensitivity rating of at least 90dB
- Outputs only 14W per channel, so partnering speakers must be compatible
- May lack a little bass and absolute power
- Not necessarily going to suit everyone's needs, it still has limitations, and will probably not suit those looking for a powerhouse amplifier or for playing rock or classical music at high levels
- Can develop a trace of hardness in loud passages that seems to restrict dynamics a little
Comparisons (according to reviewers)
- Vs Simply Italy, the Preludio is superior and is worth the extra over the cheaper model if funds permit
Takeaway: The Preludio is a well-built amplifier that offers a classy sound with good detail and natural voice reproduction. If partnered with compatible speakers, it can provide an intimate and emotive listening experience.
