Jose,
I probably heard them at the same dealer. The speakers had no spikes and placement was out into the room but just eyed into place.
The 5s are a much better speaker than the 4s but at a higher cost. Today I heard speakers from Talon, the Raven Cs and I would buy them over the 5s and over most speakers I have heard over the past several months. Why the Ravens, size, cost, faster, play louder better, more detailed sound and depth. The Dalis are somewhat smoother sounding overall but the Talons had more slam and dynamic impact. The listening took over four hours but the differences in the speakers were immediate. The Ravens are the speaker to beat for me at this point. I will be hearing the VS VR-4SEs this week and a few other name brands. I did not really want to believe that a 2 way speaker could sound as good as it did. They sound like monitors with bass. There is a Talon dealer in NYC (not sure if he has the Ravens) so if you get the chance go take a listen; hey I will go with you. They are one of the most detailed speakers I have ever heard without sounding too analytical.
The speakers were driven with very high-end tube mono block amps, and the EMC CDP. Email me directly if you want to go into more details.
Happy Listening.
