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?
