Well, I didn't elaborate on comparisons since I heard them in different systems. I don't have a reference for comparing the preamps directly. Many on this forum compare out of context but I try not to. The 99 was paired with an 88 and Tannoy D700 speakers (I believe) and the sound was lively and "friendly." The McIntosh was paired with a MC352 and Paradigm Reference 100.2 speakers and the sound was silky and just tonally correct to my ears. There was generally better focus and presence than the Rogue/Tannoy setup. Both were good but the McIntosh was better (I heard them about two months apart though...). However, as you said, the Mc is much more expensive than the Rogue. A big plus for the C2200 in your case is that synergy is assured with your 6900. If you have the money, the Mc would be a winner in your system IMO. Arthur
