Dear Jill,
Sorry to be the bearer of bad news, but the Cary and the Pass X350 are not a good match. The output impedance of the Cary is 440 ohm (single-ended); the single-ended input impedance of the Pass is 10 K ohm. In order to be a good match, the output impedance of the pre would hv to be 100 ohms or less -- even 200 ohms would not be too bad, but at 440 ohms into 10 k ohms, you'll get some loss of dynamics and some truncation of frequencies at the extremes.
Best,
Joe
