Well, I bought some 0.1% resistors and changed the loading to 400 Ohms on the AudiaFlight. I can now appreciate the unit, and at this stage I think it is faster, and has better resolution than the SimAudio. Now that the tone and the bass is sorted, it is just beautiful to listen to.
My only question is what were they thinking when they designed the loading options 7, 9, 10, 23, 30, 90, 100, 980 Ohm only!! 5 options between 7 and 30 Ohms, and then in the critical zone between 100 and 1000 Ohms only 2 options. The change in loading has transformed the sound, now to try some other values! I think I will be able to tailor the sound to my exact preference.
