The Avalon utilizes an innovative new hybrid construction method which combines point to point wiring, circuit tracing, and turret style construction. All parts, including the transformers, are identical to the ones that go into our traditional amps and are hand wired and built in our factory in Los Angeles. The result is an amplifier that produces crystal clear, dynamic, three dimensional tones that are unique to Matchless at a lower price point.
