The “[Klippel Listening Test](https://www.klippel.de/listeningtest/)” is not exactly the comparison/evaluation you’re talking about, but it is an interesting way to see to what level one can audibly detect distortion in their own system. It’s often surprising to people who’ve never tried it before. Especially when they find that while they _think_ they can hear stuff down around even -90 dB (never mind the SINAD-IS-ALL types that think anything less than 120 dB is useless), and suddenly find out they can’t reliably do it at -60 dB … Anyway, just posting it for fun/illustration. --- _[View the full topic](https://forum.headphones.com/t/bakoon-amp-13r-enleum-amp-23r-discussion/6449)._
