How much power do you need? The ARC has more dynamics, more spacious soundstage, better bass, but its upper mid/lower treble bites a bit. The C-J is more seamless, finer textured, more midrange body, but sounds smaller/less powerful; should also be cheaper by 20-30% used. Are you only looking at tubes? Marsh A400s-pretty great for 200 watts/ch solid state.
