Yes, when I said 50% as good as the best I've heard, that's about twice as good or 100% better. As a teenager and in my 20's, I did not know how advanced my audio system could sound. Many people are just not aware of how great an audio system can reproduce music. In my youth, I never considered room acoustics which was a huge mistake. Audio stores didn't talk to me about it back in the 70s and 80s.
I'm 62 now and have had much experience, including as an amateur recording/mastering engineer. I know how much better (or worse) a system can sound.
