Int. Amplifier with Focal 807W Speakers

Looking for the Integrated Amplifier that would have good synergy with the Focal 807W Speakers. My preference is smooth jazz.

So far I've tried with Simaudio NEO 250i - No details, just the bass. Arcam A19 - Slightly better details but the highs
were muffled. NAD C356 - Great sound, the only problem was
the volume gain. I barely could move the Volume knob from the
minimum and it would be too loud.

I would really appreciate your opinions.
