The Acoustic Sounds/QRP recommendations above are all excellent choices. I have most of them and they are just spectacular. Regarding Steely Dan, I'll add that the 45rpm issue of Everything Must Go is an absolute knock-out, both musically and sonically. And also, from the first release of the Pablo Series, any of the Count Basie records, but especially 88 Basie Street. Turn it up, and then turn it up some more, and the big band comes right into your room.
