I agree with Herman's statement above that the detail and dynamics are as good as it gets. The lowest octave of bass is the weak point. But everything else is so good, and there is such a small amount of lower octave used in most music, that you really never miss it, unless you are a pipe organ nut. Try to get an amp with good transformers, because that will eliminate the frequency extension problems that some people hear with the cheaper amps that have mediocre transformers in them.
I'd say the Lowther, AER, Reps-1, Fostex, and some other single drivers, like Moth Audio, Loth-X and such, are the way to go with a SET amp. There is a certain synergy between SET amps and single-driver speakers that can make this type of package sound better in some ways than any other amp/speaker combo. For this reason, it is better to go with an efficient single driver speaker, instead of an efficient 2-way.
