I'm not sure your problem would be strictly power, but that impedance dip is likely to diminish the bass performance of the SET. That speaker would seem to need SS or a powerful tube amp with current. Nothing wrong with the amp, just not an ideal match with your speaker IMHO.
ASL Explorer 805 DE/JM Lab Alto Utopia combo????
I am considering the Antique Sound Lab Explorer 805 DE 50 wpc tube amps as a second/just playing around set of power amps for my JM Lab Alto Utopias. They are currently driven by McIntosh 501's and I want to give the tube thing a whirl. I chose the ASL amps because of their price. Any comments regarding this combo are welcome.
