I picked up a CD version of one of the greatest rock albums of all time, "Who's Next" by The Who. I have carefully preserved the vinyl version for years, but by comparison it's aural muck. But when you play this reprocessed CD on the big old power stereo that takes back to the 70's, it's near Nirvana, and not the Cobain version. The CD version does justice to the lead riffs in the bass lines, rattles the house to the timbers and sends the kid scampering to her room as if I were playing the best hits of the Mamas and Papas. Particularly driving were the opening keyboard bars of Barbara O'Reilly that build into crashing bass. You can't play this stuff properly on an IPod. Maybe I should save my allowance for 'Tommy.'
