B&W (and McIntosh if you want the whole enchilada). I would also assume JBL.

So, separate system for rock?

I have spent a lot of time on the subject of different genre. I accidentally optimized for electronic music a long time ago by taking mostly electronic test disks. I realized that I made electronic sound incredible, but made all other genre sound poor.

Ultimately I changed my goal to fidelity to acoustic music (symphonic, acoustical jazz, etc) because it gave me an empirical ruler. All genre got better and better as I upgraded from then on. But you can optimize for a single music type… making it more flashy (as opposed to how it should sound)… but that generally comes at a cost.

For me optimal is to pursue real. This means details are emphasized in proportion to how they sound in the real world… as is bass. So it sounds like real music. Not overemphasis of details and slam such that background details come to the foreground, background instrument become solos, and an artificial slap of bass replaces the nuanced multiple arrival times that are experienced in real venues.

If you want to recreate the sound of an era try mimicking the equipment they used to recreate it.

For rock and roll horns can't be beat. 

Grateful Dead used Altec A7 and Macintosh.  You could recreate the wall of sound with several pairs of Crites Speaker Type CS Style B and still be way under budget.

Klipsch La Scala would be worth looking at

Volti Rival would be another consideration.but a little over 15K

After hearing Cornwall III and IV I felt they were really great with R&R. Not so much with other genres, but terrific with rock.
