At the moment I am driving my Kensington with Manley Neo-Classic 300B SE/PP with single-ended typology (11 watt). The sound is as full, dynamic an funky as with Snappers (100watt), but with better holography, midrange magic and transparency. It also handles complex music as symphonies and bass-heavy music as soul and rnb. Whatever the reason these 11 watts have no problem to play Kensington loud in my middle sizes living room.
