This is an excerpt from the Empirical Audio forum about the mod they is offering for the P-3A.
"Perpetual Technologies mods:
This transforms the PT P-3A into a superb sounding DAC, really world-class. Detailed, quiet and deep/wide soundstage. I've compared it to a modded Musical Fidelity and to the reference standard Meitner DAC and I think it is actually better for redbook playback.
A bunch of trace cuts, 20 components deleted, 26 components added.
The P1 is superfluous with these mods.
If you want a taste of what to expect, just remove the circuit board from the cabinet and play some music. It sounds a lot better this way, and this effect should not happen. After the mods, it sounds even better - and the same whether it's in or out of the box"
Does anyone have any comments on this mod, particularly how the P-1A is now superfluous.
Here is a review of the modded P-3A:
