I'm listening to another Blu Spec CD, some kind of technology that produces much more accurate music from normal CDs. It's not SACD, but the two I now have are so far above their regular CD counterparts - I mean it's a HUGE difference for the better. This one is George Szell conducting the first and third movements of the Mahler Tenth (the short third movement had never been released before), Walton's Partita for Orchestra, and Stravinsky's The Firebird - all these performances are perfection and I am just bowled over by the uptick in sound.
