The iTube2 is a tubed output stage; tube preamp; tube buffer and an impedance-matching device. Put the iTube2 before a solid-state preamp with another iTube2 after it to create the effect of tubing the whole audio chain. Or simply use the iTube2 as a preamp by itself. The iTube2 with trickle-down technology from the flagship ‘Pro’ series has been redesigned with new parts and new circuitry. Only the GE5670 tube remains.
