nothing much to say. The 581 replaces the 861. The 781 replaces the 861SE and the 781i has a built in digital preamp. You can apparently upgrade a 581 all the way up to a 781i. Oh and they play SACD too - by downsampling like the Esoteric models of last year. The cases are identical to the earlier models so no exciting visuals then! Greg, no I have not heard the SA11 at home so cannot really comment. It is on the list, as I do like DSD done properly, but as yet I have not had the time to compare. I would be very surprised if it were up to the CD7 on red book though.
