One thing I am going to try is to raise the speakers some. This is my office, so my listening position is higher than normal. I,ve read that the tweeters should be about ear level. I am going to try and raise the speakers about 2 inches. When listening the soundstage seems to be a little low.
Matt, you'll definitely want to consider this quote from John Atkinson's review of the Sophia in Stereophile:
In the vertical plane ... the speaker's balance doesn't change much as long as the listener sits with his or her ears below the top of the enclosure. Stand, however, and a large suckout appears at the upper crossover frequency, which appears to be just under 2kHz.
A suckout around 2kHz would definitely have an effect on cymbals, in the direction of dullness.
Also, note the frequency response plot for your former speakers (the CM1's) in this review. If you click on Figure 2 to expand it, you will see that most of the treble is elevated by around 5db relative to the mid-range. That is significant, and perhaps your experience with that speaker is affecting your expectations. In contrast, as noted in JA's review the Sophia's are essentially flat from mid-range through treble, aside from some small and narrow peaks and valleys.
Hope that helps,
