So for a passive power amp supply , I think the simplest explanation why a bigger transformer sounds better
is because as the load impedance decreases , the voltage rails with the bigger transformer will sag less .
..................................... Vac ( No Load ) .......... Vac ( @ 285 Watts )
AnTek AS - 3218 ........... 18.7 Vac ..................... 16.9 Vac @ 16.9 A
300 VA
AnTek AN - 6218 ............ 18.7 Vac .................... 18.3 Vac @ 15.6 A
600 VA

My transformers are running cool. I measured 2.4A AC draw at each secondary before it goes into the power supply section. Then approx 1.5A DC on the positive and negative rail. A 160VA transformer is rated in theory for 4.44A per secondary. So it looks like I am well within specs considering a class A amp is full power all the time(or something like that)
Dont get me wrong, I want the bigger transformers, just trying to understand if its worth the 180 dollars.
