About the AS125
The Line Magnetic AS125 (also marketed as Analog Sound™ AS-125) is a single-ended Class A integrated tube amplifier that has been retired from production. It is highly regarded for its use of 211 output tubes, which are prized for their warm, natural, and lifelike sound signature. The amplifier is designed to replicate the legendary Western Electric transformer technology, offering a unique blend of vintage and modern features. The AS125 is celebrated for its ability to deliver a wide soundstage, precise imaging, and deep, rich bass, making it ideal for audiophiles seeking a vintage tube sound with modern reliability. The amplifier is particularly well-suited for use with efficient speakers, such as horn-loaded designs, due to its moderate output power.
