How audio sensitive are you? I've heard great things about the combination of Sim Audio's W-5 & ML's. ...I'd suspect that Sim's Titan HT amp sounds very similar to the W-5. Its my understanding that the Titan (can be configured 2,3,5,6 or 7 channels). ...Not sure if one can buy channels as needed (upgrade) the other to look at would be CAL. But I'm not sure of the cost there.
Best of luck,
Mike
