Well if the CA 300 is similar to the CA 200, which I am guessing it is in terms of input impedance, 75k, then youre good, if it is like the CA 301 at 16k then that would not be a good match.
That output impedance of the AI 3a is spec'd at 1.2k, probably at 1000Hz, but measured 1.8k by S'phile, again probably at 1000Hz. Typically at the Frq. extremes it will be higher then that.
If you have then manual for the Classe see what it has for input impedance.
