Today I replaced one resistor in my Starsound amps. I swapped out the parasitic resistor tied to the small air core inductor that goes to a speaker output. The resistors that were in there were North Creek/Ohmite non inductive wire wounds considered one of the very best of this type and for this application. I replaced this resistor with the same value and wattage Duelund. The difference was apparent with one amp playing while hooking up the other. In my office now listening to music from the other room the sound is much more life like and resolute even at moderate levels. More punch more extension detail and transparency. I thought there would be a subtle difference that would carry thru further when I revise my speaker crossovers and their four resistor values..Lets see 4 times the difference I am hearing now with the subsitution of just one would make for a huge difference. I'm glad I already have the Duelund replacements on the way. Again as a replacement for the North Creek/Ohmites in my speakers. Tom
