@ProtegeManiac: I also pinned the FLAC as poorer quality, but since I'm going to reference some tell-tale signs which can be used to more easily differentiate some of the samples, I'll go ahead and put it in a spoiler box:     Based on my experiences, then, I think this test could be...

I've got a few more questions now:   Quote:   Do you mean that all all-pass filters cause large phase shifts, but only in multi-driver headphones? What about an L-R filter, which I've read behaves like an all-pass?   Quote:   I looked at the phase response vs impedance on...

This was very tough indeed! Even on my DT770 Pro's, however, I could pick out more details on Sample 4. Distinguishing between the others was much more difficult, but I think I've got them in a reasonable order:   Sample 4: FLAC Sample 2: 256kbps MP3 Sample 1: 128kbps MP3 Sample 3...

Quote:   Ok. Isn't IMD related to THD? I mean, isn't there a way to estimate (if not directly measure) the IMD based on a THD graph? If not, how does one measure it and what are the sonic clues that we can use to pinpoint it audibly?   -Bizzlebin

I just got back from a week out on business in the US and, after reading all the new posts, I'm glad to see the amount of discussion that took place. However, I still want to recap my first question and then―finally―get to my third one.   Quote:   I think we've established that just...

Quote:   By "decay of frequencies", do you mean the impulse response? Isn't this correlated with (or better yet, just a different way to look at the same data as contained in) the frequency response?   Quote:   I don't know if I would say the distortion is insignificant; on the...

Quote: Sure. But if the said distortion is negligible―I get the ideal flat frequency response―what else besides THD and soundstage are going to be different between any given cans at that point?   -Bizzlebin

After reading a lot of threads about using EQ, using it more myself, and comparing my own headphones to some others, I have been struggling more and more to tell the differences between cans. The better I EQ headphones, the closer they sound to each other; obvious, I know, but I am shocked by...

Quote:   I agree. I was able to tell pretty quickly within the first few seconds on my DT770 Pro (80 Ohm)'s; the clarity, sharpness, and cleanness of the sound is so much better on the lossless file. And I also noticed how helpful it was having them side by side. Going from the lossless...

I used to play EverQuest. I kept up with it for about 5 years and was a guild leader for some time on one of the PvP servers; actually, my name "Bizzlebin" comes from my main there, a Gnome wizard, and I've just kept on using it all these years. I did try out some other MMOs that came out around...

Greetings!   I've also been lurking around on Head-Fi for a number of months now, and I'm quite interesting in attending this event, too. Even though I'm about 450 km away (to the south), I think this is going to be the closest meet I can make that will occur anytime in the reasonable...
