Thank you very informative.
Could you please confirm if with a high ohmic value load (like for example used as a preamplifier) it behaves the same as with "no load"?AIYIMA A07 frequency response into 6.8 ohm, 10 ohm and no load ("open" circuit).
Could you please confirm if with a very high load (like for example used as a preamplifier) it behaves the same as with "no load" which actually is "infinite" load?
Yes, that is very unlikely, still would like to see it though for example for the case it is used to drive a pair of passive loudspeakers and active sub(s) in parallel through their high input and due to some reasons the passive loudspeakers get disconnected.Nobody would use the A07 as a preamplifier, surely.

That "no load" response would destroy piezo tweeters...
PS, Pavel what output level (1W/5W/full power) is the FR plot above taken at?
It is a pity that more in-deep tests are not performed in ASR main reviews.
Contrary to this, Hypex UcD and NCore have frequency response almost independent on load impedance.
especially measurements on a clean resistorTa (pasywna) PFFB to tylko modne hasło. Przy wysokich częstotliwościach współczynnik sprzężenia zwrotnego jest bardzo mały, a zatem szczyt przy otwartym obciążeniu jest tłumiony tylko nieznacznie, jeśli w ogóle.
Najlepszym sposobem na złagodzenie jest użycie najwyższego możliwego rezonansu LC i wytłumienie go (przekształcenie w ciepło) ze znacznym tłumikiem – rzadko pojawiają się we wzmacniaczach komercyjnych, które zwykle trzymają się zaleceń podanych w arkuszu danych.
Would you like the dirty one?especially measurements on a clean resistor
Pure resistance Now it's better? )))Czy chciałbyś ten brudny?
Może tłumaczenie Google z polskiego nie jest najlepsze.
Thank you . Yes we do expect for Topping PA5 to behave better (however not perfect) for the reason that a similar issue is pushed higher in the frequency axis. This is re Zout.Do we expect the hailed Toppings PA5 to behave better given a presumed active PFFB ?
