CJ ACT2 vs C2200


Hi All
I recently switched by Preamp from the Mcintosh 2200 to the CJ ACT2. The Power AMP is still the same the Mcintosh MC320 driving Sonus Faber Elipsas. I noticed that to get the same volume I have to raise the CJ ACT 2 to 65db as opposed to about 45 on  the C2200 (I am not sure if the units are the same) . Does anyone have any thoughts on why this is so?
Many thanks for your expertise

Jafant, sounds like he just got this one.  Why would he upgrade???  Come on.

All, thanks for the replies. Kalali it is the MC302 - that was a typo. Jalant I will look at the upgrade. Thanks for the tip.
I ma now looking at swapping out the MC302 for a CJ2550 or 2550 SE. I have heard that the 2550SES could overpower the "warmth" of the sound with "detail".  Any thoughts on this?
I have a CJ MF2550 (not the SE) and it is a nice warm sounding amp, but not real detail oriented.
