I listen to CTTE every week i never tire of it but hamburger concerto is the album to beat all prog albums, one thing Chris, i wish i had a moving coil that took only one side to break in, i play different albums over a week to get sufficient break in about 6 or 7 hours a day the missus gets a bit annoyed at times so it's good to use the old headphones which is a good way of checking the bias.
