Gentlemen- I've owned my Sonatinas since january-I love them. Everytime I see an ad for them (or my powersnakes) I always contact the owner, asking why are you selling? Stating, clearly, my intent not to purchase but for input. Never have I been told that it was due to workmanship OR SONICS. even when upgraded to something else (more expensive) they all praised the Silverline speakers; Sonata or Sonatinas. While some have found some problems, I don't think, judging by the feedback I've received, it is common place. I love them and stand by them as a music-making component in my 20k system. Mike
