CAVEAT: I have no relationship to the seller, and this is not an endorsement of this particular unit.
For those looking for a very high value, fairly inexpensive amp that would work very nicely with those older Thiel's that have a minimum impedance doesn't drop below 4 Ohms, you might want to consider this:

Obviously this amp would mate well with c-j's own ss or tube pres, that many Thiel owners of that vintage found to work well with.
