I do not feel the need to defend the Harbeths although I own a pair myself. Goatwuss has a point when he mentioned the Harbeths do not rock like the Dynaudios. What they do is they rock differently than the Dynaudios, and they do it admirably well with most types of rock music. It depends on what kind of presentation one is looking for in his/her rock music. All speakers can do rock music and it's just that some do it better(or differently) than others.
The Harbeths may be less dynamic than the Dynaudios but it can be little tricky to define which is a more neutral speaker. The benchmark of neutrality can be live music, and while most live music is very dynamic it does not do all the hifi characteristics with precision such as imaging, soundstaging etc. Live music is not overly warm, bright or analytical but has incredible slam and dynamics. Live music can also have a lot of body and density. No doubt live music is very dynamic(and the Harbeths as with most speakers fail to recreate that atmosphere) but try comparing the tone of instruments such as saxophone, trumpets, acoustic guitars on both Harbeths and Dynaudios and see which sound more like live music.
I am not sure why the topic of Dynaudios rocking harder than the Harbeths was brought up. The OP has mentioned that he mostly listens to classical orchestra and piano, and lower notes on the piano do not sound too good on the S1.4. It may be worthwhile to explore the Harbeth C7ES3 or the SHL5 as both excel in orchestra music. They sound very natural and unforced and are balanced across the frequency spectrum, which is a good thing for orchestral works. And the best part is Accuphase amps seem to match the Harbeths well. A few Harbeth owners are using the top two Class A integrated models to drive their speakers and they are extremely pleased with the results. In a nutshell the Harbeths are more organic and natural sounding than the Dynaudios, which in comparison are more precise and analytical. Both are great speakers that cater to individuals with select listening tastes and preferences.
