Int. Amplifier with Focal 807W Speakers

If you only have 1 source, you could try a passive pre/volume control. The external amp/preamp connections on the back of your nad allows you to bypass the preamp completely.

Good pickup ZD, and good on NAD for doing a poweramp input, they (integrateds) should all have this feature, and yes a passive VC into the poweramp section will cure your too much gain problem.

Check out a Musical Fidelity M6 500i. Loads of detail, volume control with .5 db steps, and bass that reproduces an upright bass in a very realistic presentation. Not in the component of the month club. At 500 watts it would grab ahold of your Focals and show you what the are and are not capable of.

About a month ago my new Focal Sopra No2's arrived! I am smitten!
My journey to select these speakers took me about six months, and I was careful to make sure my electronics were not at all shrill sounding, as I found the Focal line to be "musical", but the tweeters were not very "forgiving".
During my search I auditioned 1038BE's and the Sopra's driven by both tube and solid state electronics. In every case I found the tube equipment to sound "dull" and "restrained", to me not great qualities for these speakers.
The best electronics I heard driving these speakers was the McIntosh C50/MC452. I was fortunate enough to snag a lightly used pair for a reasonable amount. Before that, I had the McIntosh MAC6700 receiver (essentially a 200 wpc integrated, with a tuner module). I find the McIntosh equipment to sound really "smooth" and "musical". It's not everyone's "cup of tea", but I find I can listen to these Sopra's for a long time at a sitting without fatigue.

"Sopra's driven by both tube and solid state electronics. In every case I found the tube equipment to sound "dull" and "restrained", to me not great qualities for these speakers."

This would effect the mid bass with amps that can't give good current at this frequency. (doesn't account for the dullness your heard with tube.)
I read in reviews that the Sopra's have a 3.1ohm impedance at 210hz this is not tube friendly. And that's not taking in to account what the - negative phase angle might be at that frequency added to the 3.1ohm, it could go even lower in EPDR impedance. (Equivalent Peak Dissipation Resistance)
