The 1085/1033 is better in everything except for the price, I gather. Still, in audio applications I think it makes no difference if the LT317/337 is design in right and you are satisfied with 1-1.5A out.

Default lt stuff etc

In addition, note that the LT1085 (or the 3A 1083) is COSIDERABLY better than the 1033, especially in line rejection. So if you start from scratch to make a dual supply, built two independent supplies with the 1083 and connect them in series at the load point. This method also works with the LT317 of course. There will be a measurable difference in favor of the 1083, but as Peranders noted, the audibility of it is another question.
