How does a passive work, I have never messed with one. The 505 is sitting at $45 with no bids right now.

That creed seems a little steep for $600 bucks. Is it worth it?
Of the ones I've mentioned the Krell and Audible Illusions have an IEC connector to allow power cord changes. The Audible and Krell also have separate (a very good thing) power supplies.

A passive is nothing more than a switchbox with a volume and (maybe) a balance control. It may not have an AC connector unless it has some kind of output buffers (most don't).

For $600 I'd buy an Audible Illusions over the Creek any day the Sun comes up in the East.
