Anybody Driving B&W 805D3 With Firstwatt F6

Sounds like that is a great combo!

 I’ve always bought amps with at least 150-200W over the rated continuous mfgr set notes. 
  Except the Odyssey monos’ only 200W output at 8Ohm, maybe 350-375 W at 4 Ohm.  Lowest power amps I’ve owned, but they sure do drive every speaker I’ve drug through here the past months.  
They do seem to have unlimited power reserves, even when pushed hard at 3-4 Ohms for long periods!

Those amps will strain and clip very early trying to get any kind of volume from them.
