Fyne F703...anyone owns the ?

F1-12 owner here, pretty fantastic so far. Amp matching is more taste than anything. I've been using anything from a LTA to an Ampzilla with great results. Have also tried Dartzeel, Enleum (Bakoon), FirstWatt, and Pass XA25. They sound more modern than Tannoy with much better bass. 

The F704's weigh 150 lbs...each.  Is that right?

Yes,  150 pounds each. They have tremendous bass and dynamics when called for. Play classical better than any speaker I have heard. Play all genre of music with equally stellar results. Want to rock? Goodness these can rock. Want beautiful vocals or acoustic? They deliver. They are big and heavy.

Grannyring - Are you using the Circle Labs integrated with these speakers?

Oh yes. Beautiful synergy with these 96db efficient music makers.  Perfect combo. I feel so fortunate!
