Please provide a scientific explanation why Corda Classic powers these phones so well.
There can be! or may be not. I will try to give, but I'm not sure. In my opinion neither Hempel's or Solmon's models fit this question, but I'm not sure and I will try. May be Van Fraassen's one should work, but I think it will put it in a too subjective way, rylean one can do it, but it will put in an operative linguistic way. And we have't enough data to go on.
In the orthodox way of treating a Scientific Explanation, (Hempel's 1968 and later papers if I remember correctly):
The
explanandum "Corda Classic powers these phones so well" could be explicated if Corda classic output is sufficient to reach the minimal requirement of 0.346 Vrms at Impedance @ 1kHz at 665 Ohms. Giving the status of actual physical laws known.
I this case we can have a scientific explanation under Hempel's nomological-deductive model which can be as
explanans:
Initial conditions:
(C2) Output power of the amp: X at 665 Ohm when plugged to a Y Db sensitivity Headphone
(C2) "Well sounding" means low distortion THD under Z and things like that.
(C3) T1 is a well sounding phone and not distorting at Z if rightly powered (C2)
(C4) X at 665 and 1400 Ohm produce THD under Z
...
phisical laws or statements:
(L1) Some "scientific" laws, that is, for example that in HI-fi combo THD is under 2 or 4% or lower
(L2) 0,001 V at 600 Ohm produce clipping
(L2) Other electrical laws (Sorry my ignorance)
...

explanandum:
Corda Classic powers these phones (T1) so well
As you see you can have a Scientific Explanation of well sounding pair Corda+T1 if you know X,Y, (that I do not know) and we are below Z.
(minimum requirements achieved obviousely) under orthodox DN model.
I trust you when you say that sounds good paired with Corda, but, in the same way, try to trust me when I say that a well built OTL sounds good with T1.
