I've owned both Sophia 1 and 2 and they need to be driven a little to get going. I wouldn't call them a good low level listening speaker. Kharma is very good a low levels but don't sound good a higher levels. I know what you mean about the 802 really need to be cranked to sound there best.
Avalon and Verity do very well and any volume level. This tells you that the crossover design is very very good.
