Know before you buy
Class A operation means the amplifier's output transistors are always conducting, which eliminates switching distortion. This results in a highly linear, smooth, and detailed sound profile that is widely considered the gold standard for audiophile-grade performance.
The restoration process focused on longevity and reliability, specifically involving the replacement of aging capacitors and the tightening of all internal and external connectors. These steps ensure the units meet their original performance specifications and operate with low distortion.
While 25 watts may seem modest, the high-current design of the ML-2 allows it to drive many speakers with authority and grace. It is best suited for speakers with moderate to high sensitivity, though it will perform best when paired with an 8-ohm load as specified.
Yes, because these amplifiers operate in Class A, they generate significant heat during normal use. It is essential to place them on an open shelf or a well-ventilated rack with plenty of clearance on all sides to ensure proper airflow and prevent overheating.
These units feature standard RCA inputs for your preamplifier connection and robust binding posts for your speaker cables. You should ensure your speaker cables are terminated with high-quality spades or banana plugs that are compatible with the binding posts for a secure, low-resistance connection.
Each unit weighs approximately 65 pounds (29.6kg), so they are quite substantial. You should use a sturdy, dedicated audio rack or a heavy-duty shelf capable of supporting the weight and dimensions of 483 x 216 x 546mm.
