Mac MC152 vs Conrad-Johnson MF2275


I wonder if anybody have firsthand experience with this two amps (mentioned in the title). Which one have more liquid, transparent, musical, detailed sound? One of them will substitute LFD Zero III integrated I used as power amp with tube Mac preamp.

Thanx a lot! Really useful. One more things, I wonder how MC302 improved the sound of your system in comparison to MC152? Was it really your new amp., or maybe it was C2500? Obviously for 3.5K you can by more wpc then from MC152, but does it improve anything if I rarely use more then 20-25 watts of power?
The MC152 has more than enough power plus it is high current.  The MC302 gave me a slightly larger soundstage, that is pretty much it.
