McIntosh MC452/462 vs PS AUDIO BHK 250

Hi all!

I am looking for a new SS amplifier to replace my MC275.
Recently I bought some JBL 4429 speakers and I notice that they need more power to get the best.
My list is closed to those two stereo amplifiers but without the possibility of checking them previously.

Has anyone compared these two amplifiers?  I would like the amplifier had a lot of precision and detailed bass 

Thanks in advance!

Regards
