I have to disagree with Downunder, I have heard the JC-1 at a friends house multiple times and owned the SIM W-5, and there is no comparison in my mind. The bass authority and the 25watts of Class A make for a very musical amplifier, versus the detailed stark presentation with lite bass (sorry it couldn't drive or control my NHT 3.3's (4-6ohm speaker) to 21hz.
The JC-1 is more refined than the 3500 or two 3500's
