Small Amplifier; Big Credentials
With Linn Klimax Solo 500, we have maximised the potential of every cubic millimetre within Klimax Solo 500’s machined-from-solid enclosure to create an amp that is an improvement over its legendary predecessor in every conceivable way – one that, crucially, still boasts a compact form factor.

Solo 500 performs optimally from the moment it’s powered on for the first time, and throughout its long lifespan; an amplifier that can be driven hard for protracted listening sessions of wildly dynamic material, and yet remain silently cool; an amplifier with huge available power, devastatingly low noise floor, and eighty-five times lower distortion measurements than its predecessor. Solo 500 is a small amp, with big credentials.

Hybrid Cooling Matrix
Klimax Solo 500 features a brand-new thermal management system—a hybrid cooling matrix—which ensures that the amplifier remains cool and whisper-quiet at all times. During everyday use, a hard-anodised thermal plate deep mounted deep within the amp draws heat away from the internal electronics. This plate is bedecked with a series of precision-machined fins—designed and optimised with the aid of simulation software—forming a labyrinthine network of precisely measured channels. This efficient system radiates heat up and out of the amp’s casework.
When Solo 500 is pushed hard for protracted listening sessions, the hybrid cooling matrix gets really clever. Solo 500 switches to active cooling by way of two internal fans which force cool air between the fins atop the thermal plate. Controlled by an FPGA processor in real-time, the required fan speed is determined by a combination of the amp’s internal temperature and the audio signal. This ensures that the fans run inaudibly, at the lowest speed possible, whilst providing ample cooling to maintain ideal performance, listener experience, and efficiency.

With Solo 500, our latest top-tier innovations powerfully coalesce into the best compact monoblock amplifier we have ever made. The synergistic combination of Adaptive Bias Control, sophisticated hybrid cooling matrix with intelligent fan management, and Utopik power supply, results in a Class AB amplifier that is far greater than the sum of its parts, yet remarkably smaller than its counterparts. We’ve expertly miniaturised and arranged our flagship amplifier and power supply technologies inside its sleek and minimalist casework. Its neat size lends itself particularly well to active setups and scenarios where space is at a premium.
Powered by Utopik
The hybrid cooling matrix’s effectiveness is aided by a specially optimised Utopik power supply. Auto-voltage rails ensure that output from Utopik also adapts to the audio signal itself, only delivering the necessary power dictated by what’s playing and its volume. Less superfluous energy is generated, which would otherwise be wasted as heat. As a result, efficiency is improved, baseline internal temperature is minimised, and Solo 500 consumes less electricity in general.
