The original iTube became the ‘go to’ tube buffer for any and every home audio system. We have redesigned the micro iTube2 with new parts and new circuitry using trickle-down technology from the flagship ‘Pro’ series. Only the GE5670 tube remains. The micro iTube2 is a tubed output stage, tube preamp, tube buffer AND an impedance-matching device all in one. There is nothing like it. You can put the micro iTube2 before a solid-state preamp and another one after it, creating the effect of tubing the whole audio chain. Or you can choose to simply use the micro iTube2 as a very high-quality preamp by itself. The micro iTube2 sounds by and far, like a tube amplifier ‘done right with the inimitable magic of tubes.‘ Tonality and heft, especially in the mid-range and bass frequencies are increased to elevate the whole audio system from $100k to $1k. The micro iTube2 injects a serious does of tube magic into any audio system.
