I have heard both, and I own the ARC Ref 3. The Calypso is a very good preamp, and a great bargain for the price. IMHO the ARC Ref 3 betters it in a couple of ways. The biggest is in quietness. The Ref 3 is one of the quietest preamps I've ever heard, tube or SS. The Ref 3 also has a bit more refinement or air in the high's and slightly better definition in the bass. The midrange is about equal with some good tubes in the Calypso, which is more prone to tube rolling.
Is the Ref 3 twice as good? No. The law of diminishing returns is in effect. Only you can determine if the price difference is worth it to you.
