Integre 4 Integrated Amplifier


Put simply, Integre4 with its stock KT-150 tubes brings enormous and controlled power to your system straight out of the box. Our team have provided everything needed for an instant emotional engagement with your music.
In addition, a high-quality OLED display offers multiple adjustments and a state-of-the-art monitoring system acts as central digital processor and protection system by providing a soft-start for the output tubes, which will extend their useful life considerably by showing the tubes usage hours etc.
Beneath the chassis, Integre4 hides a complex and sophisticated operating system that provides constant monitoring of all tubes and high-power electronic components, protecting them from any kind of harmful damage. Bias can be adjusted manually via the built-in and high-quality current metering system and instant selectable anode current allows the use of any octal type tube – a tube rollers dream.
But the feature set doesn’t end here. Integre4’s dedicated headphone circuit fully exploits the amplifier’s power output stage in absence of any OPamps. Yes, Integre4 can act as a true high-performance headphone amplifier, too.

I played the unit for a week casually as the integre4 was factory fresh. Out of the box, you’ll be enjoying a fine tube design and recognizing typical, lovely tube signposts in its playback. A week of heavy use yields significant improvements, so, please be patient. Quality out of the box, yes, but the extra time benefits bass definition and overall refinement. The unit is shipped with a standard IEC power cord but the company’s cutely-named ‘knack’ mk2 Power Cable which accompanied the review unit looked beefy and classy. A nice match aesthetically to the integre4. I used it for the majority of the listening period, and yes, it was bump in performance over the standard IEC
