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.

I have a MC152 and find it extremely powerful, very tuneful and a joy to listen to.  It is also their most current 150 spec power amp.  I bought mine used from Audio Classics for $2900.00, a savings of $1600.00 and it looks and sounds brand new.  The Mac amp will be running long after the Rotel and Kinki are in the trash heap.  another plus is they hold their value.
