Q: "Meridian are well known for source but not well known for amp and speakers."
That is news to me. With Meridain, I would not call the speakers active, rather the D/A converter and amps are built into the speakers and they are fed a digital line signal. With Meridian, you kind of need to buy their whole system (your current amps and pre will not be needed). Meridain's system is about the best I have ever listened to and it really is world class, imo.
On another note, would you consider electrostats to be active since you need to plug them in?
