I first ran my ACI Titan II LE with the speaker level adapters, but, most of the time, I detected an annoying hum (induced from the unavoidable jumble of cables in the area).
I then ran shielded interconnects directly from my preamp. to the Titan II LE, and the hum was gone. There was a seamless integration with my Vandersteen 1Cs; the Titan II LE did a virtual disappearing act while it filled in the lowest octave and then some (similar to what a Rel Storm II had done, but more easily achieved and with significantly more slam when required).
A month later, I inserted ACI's 65 Hz. passive highpass filters between my preamp and main amplifier. After raising the crossover point a little on the Titan II LE, I've had that same integration and opened up the sound of the Vandersteen 1Cs a bit.
