If you want to rock out 70s style, then get these:

and a good record player (which will probably also breathe life into some of the 'flatter' stuff on CD from early or mid 70s). You will have an awesome 70s den. They are a bit more than the 1.6s, but not crazy. (I'm tempted to get them for a 70s garage system now that I'm thinking about this :) )
But, honestly, if you listen to Time and Whole Lotta love on a well-amped 1.6 system, I think you will have a hard time not getting the 1.6s.
