My data point:

Fronts: PSB Stratus Silveri's
Center: PSB Stratus 6Ci
Both sensitivities around 90dB/W/m

Amplifier: Bryston 9B ST

Hiss: Heard from 10'-12' away

Tried different cables, no change.

I talked to Mike myself today. He suggested turning down the gain on my amps or sources, but I have no gain adjustment on any of my components.
