I own a pair. They still blow me away. To my ears, good tube amps are best...though the SF Musica amp is solid state and the designer supposedly used solid state amps to voice them. I use two subs with mine now, but had them sasn sub for about a year and was still quite happy. It all depends on your expectations, the music you listen to, and on the size of the room. In room, the Guarneris won't do a heck of a lot below 40 Hz. but will by no means sound anemic
