It works quite well (am using it 2.1)

I cross over at about 55 and it just fills in a tad of the low end without competing with the Sierras. Love how adjustable this sub is.

I run most of my stuff through Optical to a Bifrost with Multibit upgrade and a Plinius Integrated Amp, so somewhat similar setup / chain to yours.
You're operating leagues above where I am! That said I am looking at a similar arrangement. Now that the Sierras are here the need for subwoofers becomes unavoidable. How do you handle your high/low pass duties?
