DD, it's advisable to view with a ton of salt stories floating around the internet such as the one you've described . You've said that you "imagine" that the DAC in your 1500 wouldn't do as well, but looking at reality the Asahi-Kasei 4382 used in the 1500 and 2500 has, as is typical of modern DACs, performance which is audibly flawless(again, if not affected by imagination).

Enjoy the music, not the equipment.
