Dan, system synergy is real, as much as I wish it wasn't. What that means for us is that speakers work better with some amps than with others. So even if someone loves an amp, it may not be the best match for a given set of speakers. For my tastes, the Dalis work best with an amp/pre-amp that I would classify as "smooth" rather than "edgy." Most inexpensive SS amps and pre-amps are edgy.
Similarly, not all speakers appeal to all listeners, like Dave and the Dalis. They are apparently not for him. They are, however, for others. Many others. Viva la difference.
If you can find a few nice amps to try, you'll be able to decide if the Dalis are or are not for you. When I first got the Paradigms, I was convinced that I had made a huge mistake. Out of desperation I tried a different amp (which are much easier to buy and sell and ship than speakers!) and found much relief.
