Digging into engineering details (to distance myself from asr), it looks possible to achieve the goal. Schiit messed up power section of Magni 3+. Just a little tweak would improve LM317/337’s output performance by a good margin. LM317/337 cannot drive large capacitance load and it doesn’t benefit from it. Schiit currently uses a MLCC as Cadj and this will result in voltage resonance near 5Khz. They probably tried to mitigate the problem by adding those 1000uf in parallel with MLCC. However this would only cause LDO’s voltage regulation to slow down. Those 1000uf (2200uf in heresy) is all the amp has to rely on when LDO is out of linear region. Also, if Adj pin is not isolated from input reservoir, it would increase output impedance of the LDO. This is probably why transient measured by Atomicbob looked a bit weird on both magni3+ and heresy. Sadly i cannot design a discrete amp to join the contest.
