Sierra amps with BAT VK5SE?

I hear the Sierra amps require careful matching due to their low impedence. Anyone know if the above combo would work? I have a BAT VKD5se source and Vandersteen 5's.
The Sierra amps will work with your BAT source. The amps input impedance is 100Kohms using the RCA inputs(single-ended). The 100k can drive any load. The amps impedance is low (2200ohms) when using the XLR (balanced) inputs only.If you use RCA's for your interconnects, then the amp will be a excellent match.


If you want to run balanced you'll have difficulties
These amps do'nt match up well with many pre amps
I've had several friends finally realize the problem in their system was the amps
