Know before you buy
No, the INT-250 is a pure analog integrated amplifier. You will need to connect an external DAC or a source component with analog outputs to play digital music files.
The INT-250 operates in Class A for the first 15 watts, providing the rich, nuanced detail associated with Class A designs. As power demands increase, it transitions to Class A/B, offering the high-current output needed to drive complex or inefficient speakers with ease.
Yes, the INT-250 is designed to handle demanding loads and is stable into 4-ohm and 2-ohm impedances. Its robust dual-mono construction ensures it maintains control and sonic accuracy even with difficult speaker pairings.
The unit measures 19 inches wide by 21.25 inches deep and weighs 105 pounds, so you will need a sturdy, spacious rack or stand. Because it utilizes large heat sinks for cooling, ensure the unit has plenty of open space around it for proper airflow.
The INT-250 is designed as an integrated solution with a high-quality preamp section built-in. It is not bridgeable, and it does not feature a dedicated 'power amp in' bypass, so it is intended to function as the primary control center for your system.
Yes, the included remote provides convenient control over volume and input selection. The volume control features precise 1dB steps, allowing for fine-tuned adjustments to your listening levels.
