lt1085,lt1033 vs lt317 337

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.
