If you value musicality and emotion SET is the only way to go. They only work well with high efficiency speakers such as most of the Meadowlark line to name one example. These type of speakers also seem to have the the same qualities as SET giving more emotion and musicality than those with low efficiency and more complicated cross overs. If you are more interested in high fi effects stick with SS or push-pull. If you really value music SET with proper speakers cannot be beat.
