I have had experience with both, but not together. I imagine it would be quite a good match, as I remember the Integré to be lean and clean in the bass, the general sound could be characterized as open and clear, revealing of detail but smooth at the same time. The (early) version of the Ref 3A Decapo I heard in 1993 was very generous in the bass; I haven't heard the newer versions, but if the family sound has been retained, I would imagine it would be quite the symbiotic pairing. The power is about right, too.
