The input impedance of the NC500 Hypex is 2k across the band, and can be driven by any buffer from a source that has 50ohm or less output impedance and the voltage gain needed to give you the max level that you need listen to. Once again, you have no idea!!
I'll try to get my friend who heard it yesterday to post on it.
Well I have listened to enough audio equipment for 5 lifetimes, do I win a prize? I actually know how to design an amplifier too. People who actually know something about high performance analog design (and Class D), can reference the data sheet here on the HYPEX website. Now consider the transient performance with the source 2 meters away in a high speed feedback loop for Class-D.
