Don't laugh, but the Sunfire amp would do a nice job. Tons of power, warm tonal balance. Cheers,
Get your hands on an older NY Audio Labs/Moscode hybrid amp. You can find these in 300 watt or 600 watt versions I believe. Tube gain and solid state output.
I've got an old pair of Grommes G101A tube amps that are stable down to 1.4 ohms at 100wpc continuous. If you don't need more than 101 or 102db, they would do the job if you can find a pair? Mine aren't for sale.
