Welcome to our world.
Today You clearly hear the difference. Next day You get something different. It's normal. That's why we need public tests. Still personal listening tests are informative and useful. This post has been edited by IgorC: Dec 9 2012, 19:12 |

Yes, the ABC/HR score can sometimes fluctuate. We are humans, not machines. I plotted how much the deviation can be in a graph. ![]() It says if I scored something 3.5, in 2 months later, I may occasionally score the same thing 3.0 or 4.0. And the standard deviation was 0.154 in the last Opus test. |

Yes, the ABC/HR score can sometimes fluctuate. We are humans, not machines. Oops, I forgot to say that, in the September scores(x-axis) I used RP-HT560, in the November scores(y-axis) I used RP-HJE150. These two scores were measured by two different headphones. So naturally they sound differently, rather than to say it's "fluctuation". |
