What picked my curiosity and what I found very interesting is to learn if the Running Springs Audio (RSA) flaks own any truly dymick/harmonics not screwing filtration know-how. If it so then it would be VERY interesting to merge with APS does with what RSA does.

I have no idea what RSA does but since it is plosive devised that has only caps and coils and since then claim “regulation” then it might do some minor ferroresonant filtration. I say minor as no one comment about any noise from this thing and to have a deep ferroresonant wave reconstruction they would need to over-saturate core that would have some mechanical noise. So, let pooh-pooh their comments about regulation and accept that RSA is juts passive filter with very minor regulation and buffering function, probably for a one-two periods). Obviously the RSA can’t get more voltage if it sinks and has no option against complete voltage droop (despite what they say at this website).  Pay attention – no one past any waves before and after and no one give any harmonic distortions numbers.

So, I wonder: what if to apply the RSA presumably dymick -neutral filters to the PP2000's output filters? We know that APS reconstructs the sinusoid summit and what is more important the current sinusoid. We know that it does not screw up dynamic and that is sound good. We know that it has out LC filters that semi-killing the caring frequency of D-amp amp and the nose of the own PP2000 circuit. So, why do not let the RSA filtration to handle filtration, presuming that RSA will this time care the fully proper sinusoid.  All that we need to know is how the APS takes the feedback - before the output filters of after them. If the APS’ filters are not in the closed loop then it would be easy to short the APS’s output filters and drive signal to RSA, letting see how the $5000 capacitors on sorbothane feet will handle the gob. Sure it all might be interesting if there is any true value beside all those RSA claims. Also, it is truly necessary to know what the RSA does in order to assess what kind load RSA might be and how much it would decuple the final load from APS 2000’s output.

I would LOVE to have the PP2000 do not see the specifics of it's loads but so far whatever I put between PP2000 and load did screw up sound.
