RE: Diff. Between Audible Illussion 2D & 3A

In addition to what the others have pointed to:

The 2D had one SS regulated FET supply for all four tubes, the 3 has another identical regulated SS FET supply and the 3A has yet another identical SS FET regulated supply which is dedicated to the phono stage.
The downside here is the amount of capacitance in the PS.

Power supply capacitance of the:
2D has a total of 300uf, the M3 has 500uf and the 3A has 800uf.
Another substantial difference, the M3A requires a complete tear down of the chassis to access the rear panel (jacks and series-resistors) which is not P-P soldered.


The 3 and 3A can have either a torroidal or EI core. Not sure why they go back and forth...perhaps inventory?

Cheers,
W
