Good to see you on the forum Bill. Even though we differ in our preference in this instance, I know where you're coming from & respect your viewpoint.
Putting the above aside for a moment, the S5's are the most transparent and resolving of speakers, and are very coherent. As such, they will faithfully reproduce what is fed to them without editorializing. To me, although the S5's are a bit more laid back in presentation & warm sounding than the Q3's, and are easier to place than the Alexia's for example, they still require patience and careful setup to extract their full potential. I have heard Magico speakers sound haunting with Vitus Signature Series & Siltech Royal Sig series cables, and lean and unmusical with the old Soulution amps (have heard the new series are better). Another factor previously discussed is run-in time which is long (atleast 1000hrs).
As one member eluded to above, you could walk into a Dealer's showroom and hear a not-yet-fully run in pair of S5's with something like Spectral, Boulder or Soulution and completely dismiss these speakers. Yet if you take the time to get it right (ie: built your system around the speakers and fully optimize your setup), the S5's are capable of stunning sound.
