RE: Biamp options

The downside of the Behringer is that it has a digital volume control that provides a maximum of 8 bits in its 32 bit processor for volume control before eating into the 24 bit signal. That comes to a 24 db range of control. That is too narrow a range in real use, like the difference between a symphony orchestra and a piano quartet. The chamber group is still plenty loud.

If you use a volume control before the analog inputs of the Behringer (normal preamp), then you will have to choose between having the loud portions of the signal cut off, or have the resolution drop below 24 bits. Well below, as most of us adjust volume in about a 30-35 db range. Therefore, if you set the input sensitivity to your normal high listening level, then at low level listening you will have less than 14 bit resolution. And as low as 10 bits.

The Bryston 10 is a great sounding crossover, and would get my highest recommendation unless you must have an all tube signal path.

The output stage of the Classe multichannel amp is single ended: the live is at +V and the ground is at 0. When you bridge, one amp stage does +V and the other does -V so you have double the voltage and the output is cleaner because each of the positive and negative legs has its correlated distortion and noise canceled by the other's. This provides a further increase in usable output.
