Craig, yes, Autumn Leaves is quite good. If you had a really good and fast amp, say a McCormack DNA-2 Rev A, you will notice on track 10 the piano solo on the back half of the track is out of this world. You'll need to listen closely a couple of times. As fast as that pianist is moving up and down the keyboard, you'll hear every single note individually. And you may even hear the hammers hitting the strings.
But only if you have a fast amp.
Jacintha's other XRCD "Here's to Ben" is also really nice.
