Synergies in music and amp combinations?

Rap is Schitt. Or is it Schiit? Never could get my Schiit straight. 
Anyway, Diana Krall is a singer, and a Singer is a Porsche, so I would definitely be all over that schiit.

Like all genres, there is good and bad. Meant this as a tongue-in-cheek thing, not to trigger an indictment of an entire formal of music. 

Diana Krall sounds "in the room" via my Ayre DAC/Boulder amp /ML pre-amp
Whether she is a Porsche because she is a singer, not sure. Her recording quality is awesome. ( I have often found the Verve label to have top notch recordings)

The way she sounds thrills me like driving my Porsche even though its not a Singer ( though I would love one if I could afford it)

Know very little about schitt but from what I red her, its far from crap.

Get Nas on a Boom Box save Krell for real music.

Electronics doesn't care. The better electronics will sound better with anything and everything. Electronics can't and don't favor certain genres of music; this is one of the oldest and most persistent myths in audio.
