^^^ Yes, exactly. And nulling can be used in many other interesting and creative ways. The device I’m currently developing can measure distortion down to extremely low levels, and it can even use music as a test signal. It can also compare two wires to see how they differ. So you could compare the $3 RCA wire that comes free with every CD player versus a $2,000 "interconnect" and see how similar they are. If they null to below -100 dB then you know both wires must sound identical no matter what the vendors claim. Pretty neat, eh?!
Geez, Louise. Didn’t you get the memo, Nathan? Things that measure the same often don’t sound the same. At least in the audiophile world. One assumes you’re from the bullet headed Audio Review dude’s school of thought, the one from back in the 80s who said exactly what you just said. It’s just another example of what separates Mid Fi from the high end. You want some examples of things that measure the same and sound different, you say? Capacitors, cables, power cords, power cord conmectors, resisitors, speakers, CD players, stereo cartridges, amplifiers, preamplifiers. Even electron tubes that measure and have the same military spec sound different. Imagine that. Everything sounds different. Cones sound different. Isolation stands sound different. Even one with the SAME measured resonant frequency. Follow?
Geez, even TVs that measure the same look different. Or are you blind too?
