I wouldn't make too much of that. Look at the mean frequency. You got a better test record, that's most of it. This app is useless for sorting the great from the pack. Still, an excellent performance from your WTT.
Fleib, how would you know I have a better test record? Maybe mine is worse? Many components to sound and I didn't comment on this. In retrospect, it's still very hard in some cases to determine from graphs what are better results and I cannot assume better results than the Victor but the other table results posted, likely.
How do I know? Your mean frequency is exactly 3150Hz. The VPI is 3154.5. I forget what the Victor is, but I remember it's not 3150.
Have you seen the Victor with the Timeline? It spins at exactly 33 1/3 RPM with any load. How do we explain the deviation?
Not to belittle your table, it did remarkably well, but look at the green line which is supposed to be net performance, and compare to Victor.
I wouldn't take it too seriously though. This app is really for amusement purposes only. No self-respecting lab would touch it. Kind of feel sorry for Mikey Fremer. He tries, but fights an uphill battle with Stereophile.
