Very interesting comments. I have tried in a DHT preamp the Audio Note, Shinkoh, Takman, Riken and Amtran resistors. They all sound different. I prefer the Shinkoh for a more realistic and natural. The metal film was more lively and open compared to the Shinkoh. Second to the Shinkoh was the Audio Note, very close but not as natural in tone or flesh sounding. I am able to switch the resistors on the fly as I built them into a rotary switch. Many people who have heard the preamp in "their" system agreed to my findings even though they did not know what resistor I was switching to. Not sure if I would get the same results in speakers or amplifiers as I have not tried this yet.
Happy Listening.
