Yes. I don't really think you NEED an amp with the DX-100.

Besides, the DX-100 puts out way too much power for the 
SB-220, and especially for the  Thunderbolt.

If you could crank the drive level down, you MIGHT be able 
to use the SB-220 at about 375 watts input, but that would 
only be about 4 db difference in signal level output, or 1.5 
"S" units at the receiving end.

Hardly seems worth the trouble.

I'll bet that if you try the HQ-180/DX-100 (barefoot) together, 
you will be quite pleased with the results.

I would give them a try that way before I would think about 
an amp.

And then if I really decided that I NEEDED an amp, I would 
build one along the lines of that one that Pete mentioned: a 
4-1000.
