I recently auditioned the C46/MC402 combo vs the MA6900 ina direct A-B comparison. I was prepared to buy the separates when I walked into the store. I walked out with the MA6900!!!. Both sounded great, however the integrated amp had more clarity, immediacy and was more open sounding. Speakers used for this audition were B&W Signature 805. I don't regret my decision, plus I saved several thousand dollars!
