The Line Magnetic LM-300IA is a remarkable integrated amplifier that stands out due to its high-quality components and exceptional sound quality. With a power output of 2×10 watts and its 300B single-ended design, this amplifier offers a unique listening experience for audiophiles. In this article, we will explore the specifications, features, and build quality of the LM-300IA.
High-Quality Tubes
The LM-300IA is equipped with carefully selected and matched tubes from renowned manufacturers. The input stage includes Electro Harmonix ECC81 and two Tungsol 6SL7GT tubes, while the driver stage consists of two LINLAI 274B tubes. For the power amplifier, there are two PSVANE 300B tubes that provide a rich and vibrant sound reproduction. These tubes have been chosen to maximize the performance of the amplifier in both the preamp and power amp sections.
Connections and Functionality
On the back of the LM-300IA, you will find several connections, including three pairs of line inputs and a preamp input. This preamp input allows for the connection of an external preamplifier, enabling the LM-300IA to function as a power amplifier. Additionally, there is an analog sub-out connection that makes it possible to integrate an active subwoofer. This ensures versatility in setting up your audio system, regardless of your needs.
Advanced Construction
The amplifier is equipped with specially designed, powerful toroidal transformers for power supply, as well as two EI output transformers with a high bandwidth. These transformers are carefully encapsulated and installed separately to minimize interference and optimize sound quality. Volume control is managed via a high-quality ALPS potentiometer, and the RCA connections are specially developed to reduce noise and ensure impressive signal strength.
Handmade Quality
The LM-300IA is handcrafted and features the finest point-to-point wiring. This not only guarantees excellent sound quality but also ensures a long lifespan for the device. The amplifier is finished in a luxurious, timeless piano lacquer, which not only enhances its aesthetic appeal but also emphasizes the overall build quality.
User-Friendliness
One of the standout features of the LM-300IA is the bias adjustment located on top of the amplifier, complete with a real ammeter for accurate measurements. This allows users to easily monitor and adjust the idle current as needed. Additionally, the amplifier features a soft start and a 30-second delay circuit, which benefits the lifespan of the tubes.
