I have 2 Aleph 5's I passively bi-amp Nautalus 802's and they sound wonderful. I think Alephs are some of the best sounding amps around. Inefficent, can't handle difficult speaker loads, and will double your electric bill, but wonderful sounding amps. I also have a feeling they won't last forever 'cause they run so hot. Hopefully Nelson will still be around a while to repair them!
