Mcintosh power amp for 804 D2s

Hi everyone, 
I'm new here.   I just purchased a pair of mint condition B&W 804 D2s.  It's set as speaker B mainly for music listening, and driven with a Marantz SR7012 for my home theater set up.  I would like to add a 2 channel amp only for music.  McIntosh has always been in my dream/bucket list, so I am sure that's what I want to get.  My budget is $4k-$5k.  Would a new MC152 be sufficient?  I listen mostly to classical and jazz at low to moderate volume.  However, on weekends, I like "jam it up with the kids" and listen loud to rock, hip hop, etc....so I do need the speakers to go loud.  
Or is it better to get a used, but more powerful Mcintosh like the MC252 or MC402 (which are in the $4-5k range used).  Thank you in advance for your advices.
