Tubes do have a wonderful appeal. I have a SET using EL34's that almost
duplicates the SIT-2. Power, distortion, damping are very similar. Bandwidth
is wider on the SIT.

Carefully matched AB into a pair of OB Voxatives shows only small difference,
not enough to care about.

Of course that was largely the point of the SIT-2.
