I have the basic Song3s. Delivered in August, listening to classical, old rock, folk, 'world' music, vocals. The speakers have no shortcomings in my experience, great imaging and soundstage and excellent reproduction of voice. I am using a Parasound Halo integrated and Emotiva ERC-3 with the Song3s. Both components need to be upgraded to deliver what the Song3s are capable of in terms of musicality. My next move will be to match up the Song3s with a tube integrated; thinking about the Prima Luna. Maybe a high quality transport/DAC. There is far more room for improvements to these two components than the Song3s.
