NewClassic 275 v.2 Two Channel Power Amplifier

Does anyone have any experience loading the NewClassic 275 powering four speakers rated at 4-8 ohms?  It has a 2ohm switch on the back for such speaker load.   How hot does the 275v2 get?  Maybe I should be looking at the next more powerful amp in the product line?  The NewClassic product line are attractive amps with great reviews.   

thanks
