But you can at least dress it up with new words.

Nothing you've said has been remotely rational.

Also maybe decide if spending $1,700 on friggin' 75 mA per channel is worth it

But you can listen to the non-zero results of the null test between two different DACs or filters to roughly judge whether the differences would be audible in the real world, without a controlled listening test.

ramachandra, could you possibly upload the two files you used for the ABX test so we can take a look at them? The ones downloaded straight from the artist's Bandcamp null out completely, absolutely no difference.

This isn't true, but even assuming it was you're allowed to listen to the samples as long as you want before you make a decision in an ABX test.

Hmm yes I see that's reasonable.

The volume of the video is going to be different for everyone, depending on their headphones and amp. The M50 isn't a very hard headphone to amp, so probably listening at max volume is too loud. The only way to know for sure is to measure the volume with a SPL meter. Or measure the voltage and...

It's worth the bump for 2 Chainz.   A million dollars to spend on audio? I'd get myself a house in the middle of nowhere, spend maybe a couple thousand on a good speaker system in a dedicated room, and buy about 100,000 CDs.

Didn't watch your example videos, sorry.   1. Some of the videos I've seen (SonicSense reviews mostly) play the song right from the digital files, then switch to a recording of the song played through the headphones. This seems like the way to do it, because the transducer on the user's end...

Good save

It depends on the situation. If a person wants to like a headphone (which is usually the case in this hobby, new toy syndrome etc.) minor flaws that are easy to ignore or adjust to might appear to smooth out with time. Especially if that headphone is getting most or all the head time. It's not...

Vinyl has an effective noise floor of around -70 dB at best (vinyl aficionados can correct me if this is wrong, but it's close), higher with dust on the record. 16 bit audio has a noise floor of -96 dB, about 6 times quieter. 24 bit audio has a noise floor of -144 dB, and your digital gear...

What superior models and how do you know they're superior?

The drivers are supposed to be able to handle 15 W for up to 200 ms, according to the manufacturer specs. That's a peak of nearly 143 dB based on the new 101 dB/mW sensitivity spec. Anyone got a speaker tap?

It will most likely tone down the treble and upper midrange because of fewer reflections in the cup, and trap more bass for a warmer sound. Venting the pads with holes will raise the treble back up a bit, like a bowl pad but not as extreme. You'll have to decide for yourself if it "clogs" the sound.

Almost everything you can do to the inside of a headphone's housing will affect the sound. Definitely if the felt is between the driver and the ear, but also if the felt is affecting how the sound waves reflect off the walls around the driver. How it affects the sound will depend on many factors...

The discussion is on cost to the supplier vs. markup, not on inconvenience to the consumer. I think we all agree hi-rez is considerably less convenient for the consumer in both storage space and bandwidth.

Not by nature, they can be voiced bright or dark same as open ones. It's easier to get deep and loud bass out of closed headphones, though.

Emphasis in the treble leads to increased sense of detail, speed, and soundstage. Meanwhile, it's easier for bass frequencies to mask frequencies in the midrange, leading to a muffled or muddy sound. Audiophiles tend to use these terms to separate high end headphones from low end, so generally...

20 kHz is plenty. I can't hear above 18 kHz. I've tried and tested.   Not sure what you're talking about in the next section, but it sounds conspiratorial.   Why should hi-rez be priced premium? Is it an elitism thing?   You don't need an ABX comparator to do an ABX test, it just makes it...

It doesn't, though.

I believe he means the recordings he makes are always two mike recordings, not the recordings he listens to.   I know it can be hard to decipher his posts sometimes, don't worry

Don't forget to use a CD mat or you might jumble up the order of the tracks.

Rip a CD with and without a CD mat, then ABX the resulting FLAC files with the Comparator plugin. Or hell, just compare the files in Audacity, or see if the checksums match. Easy. But, I'm sure there's some mystical reason for why this won't work as well as slowly switching CDs with a friend.
