I'm not sure how old this rotel is...but these days, B&W speakers are designed with rotel in mind ever since they became partners in the audio industry. On the same note, the amps rotel makes have B&W in mind.
B&W uses rotels to make tests and tweaks.
Rotel uses B&W as monitors to perfect thier design and components.

The co-op hasnt been very long so the I-amp you mention may not apply.
