The McCormack DNA2 (or deluxe) is rated at 300 wpc into 8 Ohms, 600 wpc into 4 Ohms, and 1200 wpc into 2 Ohms. This is a sweet powerful amp, and can be had for around $2500. used. Steve McCormack can also "optimize" this amp to drive 1 Ohm or 1/2 Ohm loads. I've used this amp (now Rev. A) for several years. Good Luck and Cheers. Craig
