Know before you buy
While 25 watts per channel may seem modest, the INT-25’s pure Class A design provides significant current, allowing it to drive a wide range of speakers with ease. It is best suited for speakers with moderate to high sensitivity, where its focus on clarity and musicality can truly shine.
Pure Class A operation ensures that the output transistors are always on and operating in their most linear region, which eliminates crossover distortion. This results in a warmer, more natural sound profile with exceptional detail and texture, particularly at lower listening volumes.
The INT-25 is designed specifically with single-ended (RCA) inputs. If your source components only offer balanced outputs, you will need to use high-quality RCA adapters or cables to connect them to the amplifier.
The INT-25 effectively combines the circuitry of the XP-12 preamplifier and the XA25 power amplifier into a single chassis. This integration eliminates the need for interconnect cables between components, reducing potential signal degradation and saving significant space in your audio rack.
The rear panel features robust speaker binding posts that are highly versatile. They are designed to accommodate spade lugs, banana plugs, or bare wire, ensuring compatibility with most high-end speaker cable terminations.
