They sound very musical driven by the Topping TP60, the NFJ&FX Audio TPA3250 (the stock PS was OK, the Astron LS10A linear PS is much better) and the Luxman LS400.
Low end is what it is for a small stand mount. Decent tonal balance and rhythm. They are a fun speaker.
I think they would sound good listening nearfield driven by the Advent 300.
